>Description:
        Linking dxexec in graphics/dx (dx-4.4.4nb4) fails with ld
        unable to find -lsz.

        This looks to be some kind of buildlink problem to me,
        libsz is installed in /usr/pkg/lib - but is not linked
        into the .buildlink/lib directory in dx's work dir.

        libsz is required ib libhdf (from devel/hdf) - hdf's
        Makefile has a .include of szip's buildlink3.mk file,
        the dependencies all appear to be there - I always knew
        I didn't really understand the rules for  bl3 stuff,
        now I have proof...

>How-To-Repeat:
        I use pkg_comp with libkver and NetBSD 4.0 release sets
        installed (with X11_TYPE=modular instead of the x* sets).
        I doubt any of that is relevant to this problem.

        Building graphics/dx (with the newly fixed devel/hdf - hdf-4.2r4)
        results in ...

        the undefined ref to libsz comes from libhdf.so (and libmfhdf.so)

        Note, as usual all this was built starting in an almost
        empty sandbox, szip (and /usr/pkg/lib/libsz.so etc that
        come from szip) was installed only because building graphics/dx
        installed a dependency that required it.

        But somehow, that didn't get through to the buildlink3 setup
        to get the library linked into the .buildlink/lib directory

>Fix:
        ??   No idea - but I'd like to...   Would whoever fixes this
        (whoever it is who understands the bl3 rules well enough)
        like to give a 2 line summary of what rule wasn't followed
        so I (and perhaps others) can perhaps suggest a fix next time
        instead of just wallowing...
