777 is not the magic sledgehammer to fix all permissions problems. 750 ought to do.
You probably don't have that application in your PATH, so it can't run anything, leaving the variable blank. . /etc/profile at the top of your script perhaps to make sure it loads a complete one.

NAME
fileutil::magic::cgen - Generator core for compiler of magic(5) files
SYNOPSIS
package require Tcl 8.4
package require fileutil::magic::cgen ?1.0?
package require fileutil::magic::rt ?1.0?
package require struct::tree
package require struct::list
::fileutil::magic::cgen::2tree script
::fileutil::magic::cgen::treedump tree
::fileutil::magic::cgen::treegen tree node
_________________________________________________________________
DESCRIPTION
This package provides the generator backend for a compiler of magic(5) files into recognizers based on the fileutil::magic::rt recognizer
runtime package. For the compiler frontend using this generator see the package fileutil::magic::cfront.
COMMANDS
::fileutil::magic::cgen::2tree script
This command converts the recognizer specified by the script into a tree and returns the object command of that tree as its result.
It uses the package struct::tree for the tree.
The script is in the format specified by magic(5).
::fileutil::magic::cgen::treedump tree
This command takes a tree as generated by ::fileutil::magic::cgen::2tree and returns a string encoding the tree for human consump-
tion, to aid in debugging.
::fileutil::magic::cgen::treegen tree node
This command takes a tree as generated by ::fileutil::magic::cgen::2tree and returns a Tcl script, the recognizer for the file types
represented by the sub-tree rooted at the node. The generated script makes extensive use of the commands provided by the recognizer
runtime package fileutil::magic::rt to perform its duties.
BUGS, IDEAS, FEEDBACK

:: magic of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883]. Please also report any ideas for enhancements you may
