It is broken (libffi from GIT, the only that works on OX 10.7):

$ make check
Making check in include
make[1]: Nothing to be done for `check'.
Making check in testsuite
make  check-DEJAGNU
srcdir=`CDPATH="${ZSH_VERSION+.}:" && cd ../../libffi/testsuite && pwd`; export srcdir; \
	EXPECT=`if [ -f ../../expect/expect ] ; then echo ../../expect/expect ; else echo expect ; fi`; export EXPECT; \
	runtest=`if [ -f ../../libffi/../dejagnu/runtest ] ; then echo ../../libffi/../dejagnu/runtest ; else echo runtest; fi`; \
	if /bin/sh -c "$runtest --version" > /dev/null 2>&1; then \
	  exit_status=0; l='libffi'; for tool in $l; do \
	    if $runtest  --tool $tool --srcdir $srcdir ; \

	  done; \
	else echo "WARNING: could not find \`runtest'" 1>&2; :;\
	fi; \
	exit $exit_status

I have installed the newly built libffi, but rebuilding guile takes a lot of time.
