Buildng ghc-devel from macports

[C.M.Brown]

Hello,

I've been trying to build the ghc-devel package (6.7) from macports.
However the build seems to fail half through. Specifically when running
the setup for base-2.1:

configure: Using compiler: ../../compiler/ghc-inplace
configure: Compiler flavor: GHC
configure: Compiler version: 6.7.20070411
configure: Using package tool: ../../utils/ghc-pkg/ghc-pkg-inplace
configure: Using ar found on system at: /usr/bin/ar
configure: Using haddock found on system at: /opt/local/bin/haddock
configure: Using ld given by user at: /usr/bin/ld
configure: No pfesetup found
configure: Using ranlib found on system at: /usr/bin/ranlib
configure: Using runghc found on system at: /opt/local/bin/runghc
configure: No runhugs found
configure: Using tar found on system at: /usr/bin/tar
configure: Using happy: /opt/local/bin/happy
configure: Using alex: /opt/local/bin/alex
configure: Using hsc2hs: ../../utils/hsc2hs/hsc2hs-inplace
configure: No c2hs found
configure: No cpphs found
configure: No greencard found
Setup: Unrecognised flags:
 --with-cc=gcc
make[1]: *** [stamp/configure.library.build-profiling.base] Error 1
make: *** [stage1] Error 2

Hope someone can help!
kind regards,
Chris.
