Ah so maybe it's not just me, and is something that could be fixed.

I will have to get back to you on the details.  If I don't get some
sleep RIGHT NOW my head is going to explode.

However, it's been over a week since I did an "svn update".  I'll do
that first then re-try the bootstrap.

If I understand correctly, the gcc upon which we build our llvm-gcc
builds itself in two phases.  First it builds itself using whatever
compiler it finds installed on the build platform, then it builds
itself again with the compiler produced in the first pass.

The errors are produced in the configure scripts from the second pass.
 That's what makes them especially hard to debug.

I have a Xen VM web server with some decent filesystem space, CPU
speed and memory.

I'll set up the buildslave in a VirtualBox VM on my laptop, then once
it is decently configured, I'll transfer it over to my server.

I really, really gotta go to sleep right now.  I won't sleep through
the night though because I am to have supper with my mother and her
twin sister.  After I get back from supper, I'll deal with it then.

If it's not to hard to set up the buildslave, I'll set one up for
Ubuntu 11.10 as well.  The "10" in the version number means October,
if I understand correctly, so it's supposed to be released soon.
