Yes, but ran into problems on CentOS 6.x. Easier time of it elsewhere.
centos vm template at the Data center I used to work at. I had tried to
upgrade the system perl and that broke the entire installation, but
eventually i found out you could setup the latest version of perl though

Basically yes. Perlbrew is one of the better build environments, but
not the only one. We have our build environment construct Perl
5.18.2, Python 3.4, Julia, and several other tools. We place our tree
into /opt/scalable.
When we build other packages (openmpi etc.) we place it into
/opt/$package/$version
Modules gives you some capability to manage things like this, though
I've (in the dim and distant past) spent many a day debugging things
that modules didn't do right. Usually errant libraries. ld.so can
turn good systems into horrible messes by doing what it was designed
to do and loading the first available shared object that matches the
"path".
As good as modules is, I've heard there can be some problems with it.
I've never had the chance to really get into it myself yet. (I've used
other, cruder methods that worked adequately in my environments). lmod
was created to fix some of these problems. I haven't looked into lmod
either, but here's an e-mail announcing the project from 2008,
explaining why it was started:
http://sourceforge.net/p/modules/mailman/message/20574873/
And an HPC Admin article about lmod by Jeff Layton:
