[ANNOUNCE] Glasgow Haskell Compiler 8.0.1, release candidate 1

[George Colpitts]

installs fine on mac but cabal install vector fails on primitive, looks to
me like gmp library is not provided

cabal install vector
Resolving dependencies...
Configuring primitive-0.6.1.0...
Failed to install primitive-0.6.1.0
Build log ( /Users/gcolpitts/.cabal/logs/primitive-0.6.1.0.log ):
cabal: Error: some packages failed to install:
primitive-0.6.1.0 failed during the configure step. The exception was:
user error ('/usr/local/bin/ghc' exited with an error:
*ld: library not found for -lgmp*
collect2: error: ld returned 1 exit status
`gcc' failed in phase `Linker'. (Exit code: 1)
)
vector-0.11.0.0 depends on primitive-0.6.1.0 which failed to install.
