Error building HEAD on OS X: missing gmp.h

I got a fresh tree from darcs of ghc+libraries, ran ./configure and make. Make failed with the following error:

"inplace/bin/mkdependC" -f libraries/integer-gmp/dist-install/build/.depend-v.tmp   --  -O -g -O2  -Ilibraries/integer-gmp/.   -I/Users/judah/Programming/dontbackup/ghc/includes -I/Users/judah/Programming/dontbackup/ghc/libffi/build/include     -- libraries/integer-gmp/cbits/float.c  || ( "rm" -f libraries/integer-gmp/dist-install/build/.depend-v; exit 1 )
libraries/integer-gmp/cbits/float.c:13:17: error: gmp.h: No such file or directory
libraries/integer-gmp/cbits/float.c:13:17: error: gmp.h: No such file or directory

Actually, this error did not cause the build to stop, but it was the earliest that I could find in the log (attached).
