I have packages installed in /usr/lib/perl5 and /usr/lib64/perl5. Some packages which I build and install go to /usr/lib/perl5 and others to /usr/lib64/perl5. My question is how to do you set the install path for a Makefile.PL, Build.PL or cpan install? I need to make sure that all packages are going to the same path – probably /usr/lib64/perl5 – and then remove the other – probably /usr/lib/perl5.
