Found it.  The symptom was cscc appearing to lock up under ia64 and other 
platforms when building mscorlib.dll in pnetlib.  What was mysterious was 
that Gowri Kumar didn't have any problems with the ia64 compiler and pnetlib 
on his system.

Turns out it wasn't locking up, but taking a _very_ long time to do the "token 
fixup" phase of compiler output on

The critical difference appears to be NFS (home directories on testdrive are 
NFS-mounted).  The token fixup phase does a lot of seeking back and forth to 
fix up the tokens, and this is very expensive under NFS.  But on a local hard 
drive (which I'm assuming Gowri Kumar was using), the overhead is mostly 

There is a work-around for this if people are interested, but it uses a lot of 
memory.  For now I'm going to leave the NFS problem in place.  I'll fix it 
properly after 0.5.2, in such a way that we should get a speed improvement 
for local hard drives too.

The long and the short of it is that all tested platforms seem to be working 
now, with a few minor quirks here and there.
