Probably not the cause of your problem, but note that if you have a
Mono from packages in /usr then installing Mono and related libraries
from source to /usr/local is generally a bad idea. For a start,
pkg-config has both /usr and /usr/local hardcoded as search paths, so
compilations against either of the two Monos can pull in references
from the other Mono, which don't then work at runtime. Please read
http://www.mono-project.com/Parallel_Mono_Environments for more info.
