Ahh, so is that different than what the following does:

# From http://search.cpan.org/~rschupp/PAR-Packer-1.013/lib/pp.pm:
    % pp -P -o out.pl file   
    % pp -B -p -o out.pl file
[download]

Neither of the resulting files would run cross-platform (e.g. when copied from 64bit laptop to 64bit machine, both running CentOS, or the other way around - 32bit to 64bit.) Even though no .so/etc were copied, the header on the file that PAR added require'd DynaLoader, which caused it to fail with an error like Undefined subroutine &DynaLoader::bootstrap called at /usr/lib64/perl5/XSLoader.pm line 111. (This is from a file generated with pp on my 64bit laptop last night and ran on my 32bit desktop here at the office.)

I spent several hours googling and trying various options, though I admit I didn't try that -X option (must have glossed over that thru my sleep-deprived hazy vision!)
