|P is for Practical|
Thank you for your answer,
I used the --lib option which is an option that I believe alows me to add lib files to my package as specified on the doc :
-I, --lib=DIR Add the given directory to the perl library file search path. May be specified multiple times. (http://search.cpan.org/~rschupp/PAR-Packer-1.013/lib/pp.pm)
or do you mean that I have to include every single file with a -l option ?
Thanks for cavapackager, I've heard of it but it didn't really seamed like the perfect answer for me... I'll give it another try tomorrow
And yes basically CentOS is like RHEL, every packaged is compiled after the RedHat packages and it is supposed to be 100% compatible...
