I got Mono from CVS and I installed it. However, I'm having trouble compiling HelloWorld: [daniel@net104 daniel]$ mcs HelloWorld.cs The assembly corlib.dll was not found or could not be loaded. It should have been installed in the `/usr/local/lib' directory. corlib.dll *is* in the /usr/local/lib directory, and LD_LIBRARY_PATH is properly set. I'd appreciate some help. Thanks a lot, Daniel.
