 On OSX Lion, using XCode 4.2 and a fresh install of macports I am unable
 to build ghc.

 Here is what I take to be the relevant portion of the build log:


 :info:configure checking for ld... /usr/bin/ld
 :info:configure checking for path to top of build tree... ghc: could not
 execute: /usr/bin/gcc-4.2

 /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_ghc/ghc/main.log

 configure complains that gcc-4.2 is not installed. Of course gcc-4.2 will
 not build on Lion, so I'm not sure if a symlink is supposed to be in place
 of what.
