The build problems I reported about the 20080921 beta are still
present:

I ran into some problems due to having gmp installed in an unusual
place.  I passed --with-gmp-{includes,libraries} to ./configure, set
$CPPFLAGS and $LDFLAGS for ./configure, and set the corresponding
-optl, etc., flags in SRC_HC_OPTS and GHC_CC_OPTS in mk/build.mk.

With all that, the first problem I hit was with utils/pwd/pwd.
./configure builds it by calling ghc without any special flags, so the
binary can't find libgmp.so at runtime.  pwd is compiled and linked
without problems; it just can't run.  So it seems the bootstrap
compiler knows where its gmp is, and is providing the necessary -L
flags, but not -Xlinker -R.  I got past this by editing ./configure to
add the necessary flags to the build command, but I wonder if turning
pwd into a C program would be less troublesome.

The next problem was with cabal-bin.  The command to build it didn't
use SRC_HC_OPTS, so that binary also couldn't find libgmp.so when it
ran.  I used this patch:

 .PHONY: all build configure

That gets me to this point:

Preprocessing library hpc-0.5.0.2...

make: *** [stage1] Error 2

I'm not sure how to fix this.  I assume there's some way to pass
SRC_HC_OPTS to cabal-bin, but I don't know how.
