I assume that you downloaded RSPerl from here https://github.com/sboehringer/RSPerl since it has been updated to work with modern versions of Perl.

I have never installed or even tried to install RSPerl but given your problems I thought you might not have seen the documentation. The (old) RSPerl main page has some information on how to install it and use it from Perl. The Calling R From Perl page is probably what you need to read though. It has more detailed information on installation, run-time configuration and usage from within Perl. After reading this, it sounds you didn't run the RSPerl.csh or RSPerl.bsh script (as appropriate) that sets up your environment to find RSPerl.

Oh! I almost forgot. Be sure to read the FAQ because it tells you how to install the modules alongside the rest of the Perl modules instead of in a separate location which should make things easier for you in the long run.
