System: NetBSD zemdatav 4.99.4 NetBSD 4.99.4 (IBOOK) #20: Sun Dec 3 23:50:54

Architecture: powerpc
Machine: macppc
>Description:
        A couple of cascading errors.  When building devel/py-ctypes
        on NetBSD/macppc, configure fails with:

configure: error: "libffi has not been ported to powerpc-unknown-netbsd4.99.4."

        The build process is not aborted by that, though.

        Looking in the code, I found that py-ctypes uses its own copy
        of libffi instead of the one in devel/libffi.  I "fixed" that
        by including devel/libffi/buildlink3.mk in the pkgsrc
        Makefile, adding

        changing LIBFFI_SOURCES to None in setup.py, adding "-lffi" to
        extra_link_args in setup.py, and manually linking ffitarget.h
        into the buildlink directory.  After that, it seems to work.
