Hi,
When I try and install mono (first time installation) i get errors refering to pkgconfig.
Yep.
It's looking for an rpm which doesn't exist or something you've installed, but installed it into /usr/local rather than /usr. The rpm checks /usr/lib/pkgconfig but not /usr/local/lib/pkgconfig for a .pc file
Personally, I'd forget about the rpms and just install from cvs. Much easier to do

TTFN
