It's a bug if it does.

If you just try to do a source build without any mk/build.mk then it
will try to do a registerised build, which is unlikely to work.

If you put

    GhcUnregisterised=YES
    GhcWithNativeCodeGen=NO
    GhcWithInterpreter=NO
    SplitObjs=NO
    GhcNotThreaded=YES

in mk/build.mk before building then it should work.


Thanks
