[Haskell-cafe] ghc-7.4 on CentOS-5.8 ?

Dear all, I need a recent ghc on a not-so-recent (?) CentOS. The ghc binary package (7.2 or 7.4) does not work because of a mismatch in the libc version. ghc-7.0 is working but when I use it to compile 7.4, it breaks with some linker error (relocation R_X86_64_PC32 ...) it also suggests "recompile with -fPIC" but I don't see how. (In this particular case, I absolutely cannot change/update the OS.) Thanks, J.W.
