How to build ghci?

Hi all, I can't seem to get ghc to build so that ghci is enabled. I've tried building the tar and I've tried the Red Hat .src.rpm, which works but doesn't enable ghci on my system. I'm using Mandrake 9.0 which comes with gcc 3.2 and gcc 2.96 I'm building ghc to use gcc 2.96 (since it chokes on Mandrake's gcc 3.2). ghci reports: ghc-5.04.2: not built for interactive use Is there anything special I have to do to enable ghci? Is there something odd / missing from Mandrke's build environment? Duncan
