Because you are redefining the FILE format ...? Use a different file handle in the second part to avoid this (replace FILE with OTHER. or whatever).
If you really are writing to the same file all the time, can't you use a multi-line format to put all of the stuff in one big write?
Or, see the warnings(3p) manual page for an introduction to disabling selected warnings. Basically, you could put "no warnings" in the second eval to get rid of this warning; you can have more fine-grained control if you require it (probably a good idea, but read up on the topic if interested).
I don't really understand why you need to "eval" these things, but that's just a side remark, and doesn't affect this particular problem.

warnings(3perl) Perl Programmers Reference Guide warnings(3perl)
NAME
warnings - Perl pragma to control optional warnings
SYNOPSIS
use warnings;
no warnings;
use warnings "all";
no warnings "all";
use warnings::register;
if (warnings::enabled()) {
warnings::warn("some warning");
}
if (warnings::enabled("void")) {
warnings::warn("void", "some warning");
}
if (warnings::enabled($object)) {
warnings::warn($object, "some warning");
}
warnings::warnif("some warning");
warnings::warnif("void", "some warning");
warnings::warnif($object, "some warning");
DESCRIPTION
The "warnings" pragma is a replacement for the command line flag "-w", but the pragma is limited to the enclosing block, while the flag is
global. See perllexwarn for more information.
If no import list is supplied, all possible warnings are either enabled or disabled.
A number of functions are provided to assist module authors.
use warnings::register
Creates a new warnings category with the same name as the package where the call to the pragma is used.
warnings::enabled()
Use the warnings category with the same name as the current package.
Return TRUE if that warnings category is enabled in the calling module. Otherwise returns FALSE.
warnings::enabled($category)
Return TRUE if the warnings category, $category, is enabled in the calling module. Otherwise returns FALSE.
warnings::enabled($object)
Use the name of the class for the object reference, $object, as the warnings category.
Return TRUE if that warnings category is enabled in the first scope where the object is used. Otherwise returns FALSE.
warnings::fatal_enabled()
Return TRUE if the warnings category with the same name as the current package has been set to FATAL in the calling module. Otherwise
returns FALSE.
warnings::fatal_enabled($category)
Return TRUE if the warnings category $category has been set to FATAL in the calling module. Otherwise returns FALSE.
warnings::fatal_enabled($object)
Use the name of the class for the object reference, $object, as the warnings category.
Return TRUE if that warnings category has been set to FATAL in the first scope where the object is used. Otherwise returns FALSE.
warnings::warn($message)
Print $message to STDERR.
Use the warnings category with the same name as the current package.
If that warnings category has been set to "FATAL" in the calling module then die. Otherwise return.
warnings::warn($category, $message)
Print $message to STDERR.
If the warnings category, $category, has been set to "FATAL" in the calling module then die. Otherwise return.
warnings::warn($object, $message)
Print $message to STDERR.
Use the name of the class for the object reference, $object, as the warnings category.
If that warnings category has been set to "FATAL" in the scope where $object is first used then die. Otherwise return.
warnings::warnif($message)
Equivalent to:
if (warnings::enabled())
{ warnings::warn($message) }
warnings::warnif($category, $message)
Equivalent to:
if (warnings::enabled($category))
{ warnings::warn($category, $message) }
warnings::warnif($object, $message)
Equivalent to:
if (warnings::enabled($object))
{ warnings::warn($object, $message) }
warnings::register_categories(@names)
This registers warning categories for the given names and is primarily for use by the warnings::register pragma, for which see
perllexwarn.
See "Pragmatic Modules" in perlmodlib and perllexwarn.
