Turned out I had multiple repo's in play. mono-basic from one repo, and mono-core from another. I removed both and ran "yum install mono-devel" and it installed fine from "epel" with all dependecies.

Hi.  I'm trying to install gmcs so that I can build gbrainy, a mental exerciser.

I am not sure what package provides, maybe mono-devel?  however mono-devel fails to install because, it says, mono-basic requires mono-core.  I have mono-core installed.  Why is this failing?

$ sudo yum install mono-devel.i386 ...-> Finished Dependency Resolution mono-basic-1.0.6-1.el5.rf.i386 from installed has depsolving problems  --> Missing Dependency: mono-core = 1.0.6-1.el5.rf is needed by package mono-basic-1.0.6-1.el5.rf.i386 (installed) Error: Missing Dependency: mono-core = 1.0.6-1.el5.rf is needed by package mono-basic-1.0.6-1.el5.rf.i386 (installed)  You could try using --skip-broken to work around the problem  You could try running: package-cleanup --problems                        package-cleanup --dupes                        rpm -Va --nofiles --nodigest $ rpm -q mono-core mono-core-1.0.6-1.el5.rf $

Any suggestions?
