I need a Linux ghc 6.2.1 built with glibc-2.4. The existing 6.2.1 RPM, built with glibc-2.3, works mostly OK, but with some programs, the generated executables barf and die on startup.

Any suggestions on how to create such a beast?

I've tried using ghc 6.4.1, for which there's a Fedora 5 RPM, to build 6.2.1 from source, but all sorts of compile errors occur.

It's not always possible to build old releases using newer releases, I wouldn't be surprised if this didn't work. Why do you need 6.2.1 specifically? Perhaps you can fix your client code and use 6.4.1 (or 6.4.2) instead? Cheers, Simon
