Thanks, Vernon, for this useful information. Some additional comments below:

I'm not too concerned about ipy.exe itself, but about being about to
use the dlls.

I'm trying to verify that the IronPython 2.7 dlls absolutely need Mono
2.8 or later. If that is true, I'll have to stay with IronPython 2.6
until the rest of the Linux distros catch up (or I make my own version
of Mono to download). Perhaps Miguel or someone from SuSE can add more
details to the dependencies for building and running IronPython 2.7?

andrew recently was talking about RPM build scripts on this list, but
I never heard a follow-up regarding if that information was being
shared:

Perhaps that is a way forward?

FYI, the latest LTS Ubuntu is 10.04. Which means (I think) that the
next LTS Ubuntu is due in 2012 (12.04). (Vernon corrected in separate
email the point that Ubuntu is shipping with Mono 2.6.7 as the current
version.)

I need a solution for general installs. Perhaps a stand-alone Mono
2.10 install will work, if I can't build IronPython 2.7 on Mono 2.10,
and then run with Mono 2.6.7...
