errors and strange behaviour when compiling perl script

Question

I've a perl script and when I compile it with perl2exe it gives the following message:

Can't locate unicore/Heavy.pl in @INC (@INC contains: PERL2EXE_STORAGE c:\tools\hunalign\scripts\sentence_splitter C:\Users\EURIDE~1\AppData\Local\Temp/p2xtmp-5936) at PERL2EXE_STORAGE/utf8_heavy.pl line 176.

I have the file in the unicore module, so I don't know what the problem is. However, I could temporarily overcome this by inserting this line:

#perl2exe_include "unicore/Heavy.pl";

now it compiles without error, but the exe works a bit different than the original exe compiled by the maker of the program. (It's a parser that segments sentences, and my exe doesn't segment at full stops). May it be due to a limitation of the free version of perl2exe? Any ideas?

CODE (both for original build and my own)

Can't locate XYZ in @INC means Perl is unable to find XYZ module in @INC. This means either the module is not installed or its path is not searchable, you need to add the path to your module to @INC.

See the below threads:

1. How is Perl's @INC constructed? (aka What are all the ways of affecting where Perl modules are searched for?)
2. How to change @INC to find Perl modules in non-standard locations

Using #perl2exe_include "unicore/Heavy.pl"; solves the issue because it specifies the path of module hence Perl knows where to look. (perl2exe adds the module to the executable).

exe works a bit different than the original exe

You should share your code else how'd we know what was original and what is current?
