Time to put ${PTHREAD_LIBS} in the x11/xscreensaver-gnome?

The problem isn't with the -demo binary, but with the hacks that the
binary loads.  On my -CURRENT system, libGL is linked to libpthread, and
so are my GL-based hacks:

ldd /usr/X11R6/bin/xscreensaver-hacks/glplanet
glplanet:
        libgdk_pixbuf_xlib-2.0.so.400 =>
/usr/X11R6/lib/libgdk_pixbuf_xlib-2.0.so.400 (0x280ab000)
        libgdk_pixbuf-2.0.so.400 =>
/usr/X11R6/lib/libgdk_pixbuf-2.0.so.400 (0x280ba000)
        libm.so.2 => /lib/libm.so.2 (0x280cd000)
        libgobject-2.0.so.400 => /usr/local/lib/libgobject-2.0.so.400
(0x280e5000)
        libgmodule-2.0.so.400 => /usr/local/lib/libgmodule-2.0.so.400
(0x28118000)
        libglib-2.0.so.400 => /usr/local/lib/libglib-2.0.so.400
(0x2811c000)
        libiconv.so.3 => /usr/local/lib/libiconv.so.3 (0x28191000)
        libGL.so.1 => /usr/X11R6/lib/libGL.so.1 (0x2827d000)
        libGLU.so.1 => /usr/X11R6/lib/libGLU.so.1 (0x282db000)
        libpthread.so.1 => /usr/lib/libpthread.so.1 (0x2834d000)
        libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x28370000)
        libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x28378000)
        libXt.so.6 => /usr/X11R6/lib/libXt.so.6 (0x2838d000)
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x283d5000)
        libXmu.so.6 => /usr/X11R6/lib/libXmu.so.6 (0x2848f000)
        libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x284a3000)
        libc.so.5 => /lib/libc.so.5 (0x284b0000)
        libintl.so.6 => /usr/local/lib/libintl.so.6 (0x2857b000)
        libstdc++.so.4 => /usr/lib/libstdc++.so.4 (0x28584000)

I bet if you rebuilt xscreensaver without GL support, it would work
fine.  I think adding PTHREAD_LIBS to the build may be the obly way to
fix this for libpthread users.  

Of course, as a test, you might try libmapping libthread to libc_r, and
see if you can reproduce this, Alexander.  I can try the same thing.  I
know I can.
