What “32-bit vs. 64-bit” dependent features there may be, are likely to be either in the compiled Perl executable itself, or in the less-obvious compiled (“XS”) components which make up some of the various CPAN libraries that may be installed on your system at any particular time.

So, just be sure to install Perl and whatever else you may need onto the target system; don’t just copy, say, the library-directories from one to another.   The installation process not only constructs the library in the appropriate (possibly target-dependent) way, but also self-tests each and every one to be sure that it actually blooms where it is planted.
