>Description:
        As I understand it, the theory of mk/xaw.buildlink3.mk is that
        one may set XAW_TYPE to select which variant of the Xaw library
        applications should use (the basic one, the 3d extensions, or the
        xpm extensions on top of that).

        In my /etc/mk.conf I have
                jade$ grep XAW /etc/mk.conf
                XAW_TYPE=3d

        And when making xfig, I do see ...

=> Required installed package Xaw3d>=1.5Enb1: Xaw3d-1.5Enb2 found

        The last (included) line there looks right.

        Yet, the compiled xfig doesn't look very 3d, which might
        not be surprising given ...

jade$ ldd work.jade/*/xfig
work.jade/xfig.3.2.5-alpha5/xfig:
        -ljpeg.62 => /usr/pkg/lib/libjpeg.so.62
        -lX11.6 => /usr/X11R6/lib/libX11.so.6
        -lXext.6 => /usr/X11R6/lib/libXext.so.6
        -lXpm.4 => /usr/X11R6/lib/libXpm.so.4
        -lz.0 => /usr/lib/libz.so.0
        -lm.0 => /usr/lib/libm387.so.0
        -lm.0 => /usr/lib/libm.so.0
        -lpng12.0 => /usr/pkg/lib/libpng12.so.0
        -lXi.6 => /usr/X11R6/lib/libXi.so.6
        -lICE.6 => /usr/X11R6/lib/libICE.so.6
        -lSM.6 => /usr/X11R6/lib/libSM.so.6
        -lXt.6 => /usr/X11R6/lib/libXt.so.6
        -lXmu.6 => /usr/X11R6/lib/libXmu.so.6
        -lXaw.7 => /usr/X11R6/lib/libXaw.so.7
        -lc.12 => /usr/lib/libc.so.12

        Notice the penultimate line, if Xaw3d were being used,
        what should be there would be /usr/pkg/lib/libXaw3d.so.7

        And indeed, the link command for xfig just has -lXaw which
        cannot possibly find Xaw3d (of course, the intended use of Xaw3d
        was that the installed library be called libXaw.* and simply
        replace the standard X version, but that's not now pkgsrc
        installs it - which has the advantage that different applications
        can use different styles).

        If I relink (only) xfig with -lXaw3d instead of -lXaw then
        the 3d appearance "appears" (and what's more a bug I was looking
        for in xfig vanishes - which suggests either a Xaw problem, or
        an interaction/interface problem between xfig and modern Xaw
        libraries - but that's for another day - the Xaw3d version also
        dumps core when it shouldn't, which is more serious, but perhaps
        it should also have been compiled with different .h files).

        I haven't tested setting XAW_TYPE to xpm, but I doubt that would
        behave all that differently.

>How-To-Repeat:
        As above - simply set XAW_TYPE=3d and try building xfig
        expect a (mostly) working xfig, bit not using the 3d library
        at all (though it does have a dependency registered upon it).

        Note that xfig (almost) expects to be built with the 3d version
        of Xaw (that might be what the developers atually use, from
        reading between the lines of the readme files and such), so it
        should all "just work".   It does link correctly, and much of
        it runs correctly when Xaw3d is used.
