This might be completely off-topic, but have you tried using a VM to
build LFS? I have seen some portable versions of VirtualBox on the
Internet, and using a live cd to build the system inside a VM might
solve some problems. After that, it would be up to you to prove that
your system is better than the Redhat systems still in use at your
company.
I've not tried that, but I suspect that our sysadmin would frown on it. He's on
vacation now so I can't say for sure.
Our ability to upgrade has a lot of dependencies on existing software. We're
forced by various limitations to use an old version of IC design software from
Cadence Design Systems. That in turn is qualified only on Redhat RHEL5, which
is ancient by today's standards. So my system can't be upgraded until we begin
using the latest Cadence software. Welcome to the world of corporate computing.
All I really want to do is compile the latest version of Octave, but that
depends on many other programs, most of which have to be a fairly late version.
For example, Octave depends on newer versions of gcc and glibc, as well as many
Fortran programs. RHEL5 has versions too old to work.
At any rate, I've learned a hell of a lot by this exercise and am about 99% of
the way there in completing the latest LFS system, but installed as a user not
as root.

Then my first suggestion would be to ask the sysadmin about testing the
latest version of the software you're using, or test it yourself. If it
works as good or better, then see about convincing them to upgrade
everything to its latest version. You could also make the case that many
of the updates are security updates, and they could be incredibly
vulnerable the longer they wait to upgrade.
Otherwise, if you have a computer at home, you could still use a VM to
install Fedora (the freely available version of Redhat) and run Octave,
or even to build LFS from a live cd and have a custom system without any
changes to your natively installed system. (Or if you have Linux on the
home computer anyway, you could just install Octave there, unless it
/has /to be at work. And if you have no other computer, I don't know how
else to help, sorry.)
