Well, I have port installed 7.8.3 as it needs an existing GHC, then I
unpacked 7.8.4 from tarball and...............
checking whether bootstrap compiler is affected by bug 9439... You are
using a new version of LLVM that hasn't been tested yet!
We will try though...
/var/folders/15/fqzwrj1n32gfgx8yy5t8v1bc0000gq/T/ghc7339_0/ghc7339_6.s:3:2:
error: unknown directive
.macosx_version_min 10, 0
^
<no location info>:
Error running clang! you need clang installed to use theLLVM backend
(or GHC tried to execute clang incorrectly)
failed to compile
Is that a problem??? It seems to have run the configure script just fine
for all of that.
