Thanks for the quick reply, but if I change DYLD_LIBRARY_PATH for
DYLD_FALLBACK_LIBRARY_PATH mono will not find any dll again.

Maybe I have express the problem in a not so clear way: I do not want to use
serveral verisons of libgdiplus, but only one, the one that is ok for mono
(the only software in my system using this library).  I installed the
macport version of libgdiplus, but I don't know if there are another
versions that  work better with the developement snapshot of mono. Do you
have some hint on this?
