I tried --extra-include-dirs=/usr/include (the directory where the real
Block.h resides) and there was no change. Adding the -v flag showed
cabal trying to build with this line:
/usr/bin/ghc -Iportmidi/pm_common -Iportmidi/pm_mac -Iportmidi/porttime -I/usr/include -package base-22.214.171.124 -optc-msse2 -optc-O2 -odir dist/build -c portmidi/pm_mac/pmmacosxcm.c
Since it still picked up the GHC Block.h instead of
/usr/include/Block.h, it seems as though ghc searches its own headers
before those specified with -I. I suspect if I had a way to change
that, it would work.
