Comment(by ryandesign@…):

 On Tiger/Intel, ghc @6.10.3_7 (with or without the +cabal_configure_debug
 variant) says:

 {{{
 checking for path to top of build tree... gcc -I. -I/mp/include -c
 /tmp/ghc9619_0/ghc9619_0.s -o pwd.o
 gcc: Error: You should be using ${configure.cc}
 See http://trac.macports.org/wiki/UsingTheRightCompiler
 }}}

 That's these lines in the configure script:

 {{{
 { $as_echo "$as_me:$LINENO: checking for path to top of build tree" >&5
 $as_echo_n "checking for path to top of build tree... " >&6; }

 if test ! -f utils/pwd/pwd && test ! -f utils/pwd/pwd.exe; then
   cd utils/pwd
   rm -f *.o
   rm -f *.hi
   rm -f pwd
   rm -f pwd.exe
   $WithGhc -v0 --make pwd -o pwd
   cd ../..
 fi
 }}}

 $WithGhc presumably is the ghc-bootstrap/bin/ghc binary, and I can
 replicate the problem myself running that command, if I set up the
 environment the same:

 {{{
 cd $(port work ghc)/ghc-6.10.3/utils/pwd
 PATH=/mp/bin/no_default_gcc:/bin:/sbin:/usr/bin:/usr/sbin \
 DYLD_LIBRARY_PATH=../../../ghc-bootstrap/lib:/mp/lib \
 ../../../ghc-bootstrap/bin/ghc -v0 --make pwd -o pwd
 gcc -I. -I/mp/include -c /tmp/ghc9734_0/ghc9734_0.s -o pwd.o
 gcc: Error: You should be using ${configure.cc}
 See http://trac.macports.org/wiki/UsingTheRightCompiler
 }}}

 So ghc-bootstrap/bin/ghc is itself running "gcc". Would that maybe be
 fixed if this ghc bootstrap had been compiled with the --with-gcc flag
 pointing at the right compiler, or is there maybe a runtime switch that
 can be given to ghc to tell it where gcc is?
