Sorry, didn't mean to sound like "teaching granny too suck eggs". Sometimes it's one of the most obvious of omissions.
Anyway, I'm presuming that you are compiling i.e. installing something from source?
I ask this because in the same way you can snag's when installing "non-mandrake" rpm's leaving you in "RPM hell", you can get a similar problem installing from source.
Post the stuff that appears in the terminal when you are trying this. Then either me (unlikely, I don't bother installing much in this way) or someone else may be able to identify what's going wrong.
