I'm on GNU/Linux, so it would be LD_LIBRARY_PATH for me.  Yes, that
would be another useable workaround for pwd.  What about the other
problems I mentioned?  Regardless of my problems, it seems like a
build bug that SRC_HC_OPTS isn't used for some compilations.  Is
SRC_HC_OPTS meant to be used for all Haskell compilations in the build
process, or am I misunderstanding its purpose?
