These seem to be problems that will be fixed in our next release, which
will happen when our regression tests pass (hopefully that won't take too
long). Until then, however, a fix for the second error is change the
linker flags in hake/X8_32.hs as the following patch:

diff -r 8c28b2e5d3fd -r 95e53288bd43 hake/X86_32.hs
