It looks like a problem with the binary distributions.  They include gmp, 
but somehow don't install it.  As a workaround, you can take gmp.h and 
libgmp.a from from the binary tarball and put them by hand into 
/usr/local/lib/ghc-6.8.1 (or wherever you installed it).  Alternatively you 
can install a suitable gmp package using your OS's package manager (you 
didn't say which flavour of Linux you're on).

BTW, a better place to ask questions about GHC is 
glasgow-haskell-users at haskell.org, you're more likely to get a quick answer.
