>Description:
        The latest version of net/wpa_supplicant (wpa_supplicant-0.7.1)
        fails to link with an openssl related undefined symbol.

        It might be that the openssl in NetBSD 4.0 is too old for
        this version of wpa_supplicant, and the package, perhaps
        pkgsrc machinery, isn't detecting that and requiring the
        pkgsrc version of openssl.   Might be...

>How-To-Repeat:
        I use pkg_comp with libkver and NetBSD 4.0 release sets installed
        (except the x* sets, I use pkgsrc modular xorg (X11_TYPE=modular)
        instead.)

        In that environment, expect to see ...

        I didn't expect it to help, as the buildlink3 stuff will
        (correctly) ignore it (and it did), but I tried manually
        installing security/openssl which (kind of) succeeded - for
        why "kind of" see a subsequent PR - it succeeded well enough
        though that it would have been able to be used here, if pkgsrc
        would just use some random package that's lying around without
        it being listed as a dependency (it doesn't, and it shouldn't,
        but this test was just 10 minutes of extra waiting, so harmess...).

>Fix:
        When I first saw this, I thought that perhaps I could just
        (conditionally upon NetBSD 4) .include openssl/buildlink3.mk
        and that would magically fix everything.   Then I saw that
        that bl3.mk file was already unconditionally included (but
        just does nothing).   I guess pkgsrc thinks "this is NetBSD,
        it has openssl in base, don't need another" and ignores it.
        But for this package, it appears as if that might be incorrect.

        I suppose now that some kind of PREFER_PKGSRC trickery,
        depending upon NetBSD 4, might fix it, but that's getting
        beyond my abilities...
