But I suspect it really means what it says -- the file really, genuinely isn't there. Look very closely for typos.
Wow... Yeah, the actual filename was "getIDs.plx", my code said "getIds.plx", and the code I posted didn't have the 'g'... Thanks for pointing that out!

imager::probe
Imager::Probe(3pm) User Contributed Perl Documentation Imager::Probe(3pm)
NAME
Imager::Probe - hot needle of inquiry for libraries
SYNOPSIS
require Imager::Probe;
my %probe =
(
# short name of what we're looking for (displayed to user)
name => "FOO",
# pkg-config lookup
pkg => [ qw/name1 name2 name3/ ],
# perl subs that probe for the library
code => [ &foo_probe1, &foo_probe2 ],
# or just: code => &foo_probe,
inccheck => sub { ... },
libcheck => sub { ... },
# search for this library if libcheck not supplied
libbase => "foo",
# library link time options, uses libbase to build options otherwise
libopts => "-lfoo",
# C code to check the library is sane
testcode => "...",
# header files needed
testcodeheaders => [ "stdio.h", "foo.h" ],
);
my $result = Imager::Probe->probe(\%probe)
or print "Foo library not found: ",Imager::Probe->error;
DESCRIPTION
Does the probes that were hidden in Imager's Makefile.PL, pulled out so the file format libraries can be externalized.
The return value is either nothing if the probe fails, or a hash containing:
o "INC" - "-I" and other C options
o "LIBS" - "-L", "-l" and other link-time options
o "DEFINE" - "-D" options, if any.
The possible values for the hash supplied to the probe() method are:
o "pkg" - an array of pkg-config names to probe for. If the pkg-config checks pass, "inccheck" and "libcheck" aren't used.
o "inccheck" - a code reference that checks if the supplied include directory contains the required header files.
o "libcheck" - a code reference that checks if the supplied library directory contains the required library files. Note: the Makefile.PL
version of this was supplied all of the library file names instead. "libcheck" can also be an arrayref of library check code
references, all of which must find a match for the library to be considered "found".
o "libbase" - if "inccheck" is supplied, but "libcheck" isn't, then a "libcheck" that checks for "lib"libbase$Config{_a} and
"lib"libbase.$Config{so} is created. If "libopts" isn't supplied then that can be synthesized as "-llibbase". "libbase" can also be an
arrayref of library base names to search for, in which case all of the libraries mentioned must be found for the probe to succeed.
o "libopts" - if the libraries are found via "inccheck"/"libcheck", these are the "-l" options to supply during the link phase.
o "code" - a code reference to perform custom checks. Returns the probe result directly. Can also be an array ref of functions to call.
o "testcode" - test C code that is run with Devel::CheckLib. You also need to set "testcodeheaders".
o "testcodeprologue" - C code to insert between the headers and the main function.
o "incpath" - $Config{path_sep} separated list of header file directories to check, or a reference to an array of such.
o "libpath" - $Config{path_sep} separated list of library file directories to check, or a reference to an array of such.
o "alternatives" - an optional array reference of alternate configurations (as hash references) to test if the primary configuration
isn't successful. Each alternative should include an "altname" key describing the alternative. Any key not mentioned in an
alternative defaults to the value from the main configuration.
