[Mono-list] Error building from master

[Matt Calder]

Rodrigo,

Thanks for the quick response. As near as I can tell, what happened is
this. Yesterday, I accidentally built/installed monodevelop using a prefix
of /usr/local (I typically install using a prefix of /usr). I removed that
by hand and quite possibly removed a piece of mono. Coincidentally, Ubuntu
upgraded mono this morning. In fact, it was that the prompted me to rebuild
mono from master knowing that what Ubuntu offers is typically a bit behind.
One or a combination of these events left mono in a bad way and the
bootstrap process was broken. I uninstalled the Ubuntu mono packages,
reinstalled them, and rebuilt mono and am back in business. Thanks again
for the quick response.

Matt
