building against gmp in a nonstandard location

[Paul Jarc]

I'm having some trouble building ghc against gmp installed in an
unusual place.  (Actually, I install every package in its own
directory, but gmp seems to be the one causing trouble here.)  First
attempt: adding the necessary -I, -L, and -Xlinker -R options to
CPPFLAGS/LDFLAGS when invoking ./configure, and I also created
mk/build.mk to add the -I flags to SRC_CC_OPTS and SRC_HSC2HS_OPTS,
and -optc-I, -optl-L, and -optl-Xlinker -optl-R flags to SRC_HC_OPTS.
This method worked for ghc 6.6.1, but 6.8.2 gives me:

Second attempt: CPPFLAGS, LDFLAGS and mk/build.mk as above, and I also
gave --with-gmp-{includes,libraries} to ./configure.  This ends with
the same error.

Third attempt: all of the above, plus I modified mkdependC.prl to omit
dependencies on absolute paths.  (I suspect this is wrong, since I
assume other people have successfully used gmp in a nonstandard path
without having to patch anything, but anyway...)  New failure:

I would have thought the SRC_HC_OPTS options I put in mk/build.mk
would be used for this compilation, but apparently not.  Does anyone
see where the problem might be?
