Check that same versions of needed software are installed wherever the software-over-NFS would be used that were used to build the software (perl & modules) in question.

Run some incantation of ldd /path/perly/binary-file (on the NFS server) to find the dynamically linked libraries, in order to update the lacking hosts that would run software-over-NFS. Use your OS package manager to list the installed, missing, version-mismatched software.

I sense that "portable" is so of different definitions, degrees of portable-ness.
