Comment:
I'd be really happy if someone took ownership of this problem and drove it
to a solution. @thoughtpolice?
As I understand it, currently the situation is that you have to install
gcc. We can probably make it so that you don't have to install gcc to
''use'' GHC, but still need gcc to ''build'' GHC, because we don't have
access to fast TLS support on OS X (or alternatively you can build GHC
with clang, but the GC will be slow.) It seems certain privileged
projects do get fast TLS support (WebKit), but it's not officially
available for general use.
