PerlApp does exactly what you want, but behind the scenes. you should look into --add to include extra modules in the exe. It extracts them in $ENV{TEMP}/PDK and sets the lib to there. (yeah this skips some detail) I really would like to see the technique you're using on this.
One thing to note is that PerlApp and Perl2Exe dont compile your app per se. they simply put every file needed in a self-extracting wrapper. You can also embed files in the exe and use a module (sorry don't know exactly.. PerlApp.pm maybe?) to pull the files back out at runtime.

Hope I helped!
