Short answer, not a problem.

cpan will install the module in /usrlocal, where Perl will find it 
before the module installed from an rpm. (See output of perl -V). cpan 
does not have an uninstall option, so if there's an rpm with a later 
version, and you install it, perl will not see the new module unless 
you remove the one you installed with cpan. Removing the cpan-installed 
version should not be a problem, unless the module is very complicated. 
cpan leaves the source for the installed module in ~root/.cpan/build; 
your module might have a make uninstall, if you're lucky:-)

Good luck.
