OpenAL builds despite --disable-openal (was: Error building GHC: can't locate import `Package')

I wrote:

I deleted it and said "make" again, and now it seems to work (it's still building).

As it turned out, the build does not succeed. It fails while trying to build OpenAL: | Sound/OpenAL/AL/BasicTypes.hs:63:15: | Not in scope: type constructor or class `HTYPE_ALFLOAT' | | Sound/OpenAL/AL/BasicTypes.hs:66:16: | Not in scope: type constructor or class `HTYPE_ALCLAMPF' | | Sound/OpenAL/AL/BasicTypes.hs:69:16: | Not in scope: type constructor or class `HTYPE_ALDOUBLE' | | Sound/OpenAL/AL/BasicTypes.hs:72:16: | Not in scope: type constructor or class `HTYPE_ALCLAMPD' | <> | make[2]: *** [Sound/OpenAL/AL/BasicTypes.o] Error 1 | make[1]: *** [all] Error 1 | make[1]: Leaving directory `/usr/local/src/ghc-current/libraries' It shouldn't even build OpenOL, however, because I ran ./configure with "--disable-openal". I see the flag in "libraries/config.log", so it has been passed through alright. But ${SUBDIRS} contains the "OpenAL" directory nonetheless afterwards. Any ideas how to fix this? (Except for manually editing the makefile?) Peter
