Wishlist: Allow use of standalone perl installation

[mrmuskrat]

It would be nice if we could optionally use a version of perl other than the one installed with the OS and to install the modules via cpan or cpanm.

Example:
Fedora 23 installs perl 5.22.1 with the executables in /usr/bin and the libraries in the following directories:
/usr/local/lib64/perl5
/usr/local/share/perl5
/usr/lib64/perl5/vendor_perl
/usr/share/perl5/vendor_perl
/usr/lib64/perl5
/usr/share/perl5

I compiled another copy of perl 5.22.1 into /opt/perl (binaries and libraries) so that there is virtually no way that I can mess up the system perl and break any of the OS tools that happen to use the system perl. I'd like to be able to tell dap-perl to look for modules under /opt/perl/lib and to use the cpan or cpanm app from /opt/perl/bin.
