First, yes, I would be happy to install the whole gcc 4.5 ball
of wax.  (For example, that's why I uninstalled gcc 4.4.)  But
I don't know how to do it.

Also, I am willing to take some risk.  This is a new (read
throw-away) install of ubuntu, so if something gets totally
messed up, I can start over from scratch.

You speak of the r.t.e.  Would that be the runtime environment?
I wouldn't mind blowing out the whole gcc runtime environment,
unless that would break essential ubuntu functionality.

But I would also be happy to install 4.5 along side 4.4, but I
don't know how.  Back in the steam-powered days, I would
have found a tar file of a binary gcc build, and un-tarred it in
a directory of my choice.  But the files I've located that appear
to contain gcc binaries are these ".deb" files, and I don't know
what to do with them, other than run them through the "Ubuntu
Software Manager."  And I don't know how to coerce "Ubuntu
Software Manger" to install them (let alone install them along
side 4.4) because it complains about the various dependency
conflicts.

As you can see, I don't really know where to start with the
whole ubuntu package-management process.

Thanks for help and for any further advice.
