[CentOS] can't install mono-devel because mono-basic requires mono-core. But I have mono-core! What to do? I need gmcs.

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

 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?

Thanks,
