Yes, but we're just barely looking into moving to RHEL 6 and so it will be
a while until we'd consider moving to RHEL 7 and so I think that having a
long term solution that works on RHEL 5/6 is a good thing since both still
have quite a bit of life left in them.

RedHat is making GCC 4.7 available for RHEL 5/6, but it's not available as
part of the EPEL or any other standard source for CentOS:
Maybe it'd be worth trying to get that to be available in some sort of
standardize way and make it a dependency instead of bundling GCC with the

I just like the source way better because it means that everything is from
a known source. Some users get worried about distribution of binary blobs
and when it's build from source and they can build it themselves, then it
eases those concerns.

Great! I'll check those out and see what I can get up and running.
Thanks for all of your help,
