To encourage porting efforts to Lion, I setup a computer with the
latest OS and XCode 4.1 on it.
I made an account for you:


It's actually exactly the same credentials you had for
bsd.math.washington.edu, with your files from there:

By the way, Mike Hansen was able to build the PARI that is in Sage
(along with its dependency MPIR) on this machine and it works:
