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?
