[pm-h] Linux Distribution Selection

[Matthew Dees]

For redhat systems you can use software collections (which are funded and
maintained by redhat) for getting better versions of perl.

for example, if you 5.20 on c6 or c7, you can use the following packages:
https://www.softwarecollections.org/en/scls/rhscl/rh-perl520/

or 5.16:
https://www.softwarecollections.org/en/scls/rhscl/perl516/

There are some extra bits you'll have to do your shebang to ensure your
scripts work properly, either writing your scripts with "#!/usr/bin/env
perl" and using the scl command to enable the correct version of perl or
specifying the full path to the perl executable
"/opt/redhat/rh-perl520/root/usr/bin/perl" in the shebang.

If you're doing an /opt install, might as well use one where someone has
already done the work for you.
