>Description:

make in graphics/MesaLib bombs linking .libs/libGL.so.1.0.5 with

        /usr/bin/ld: cannot find -lX11

The offending link line is

        /disk/disk0/pkgsrc/graphics/MesaLib/work/.gcc/bin/gcc -shared
          [lots of .o files]
          -L/disk/disk0/pkgsrc/graphics/MesaLib/work/.x11-buildlink/lib
          -L/disk/disk0/pkgsrc/graphics/MesaLib/work/.buildlink/lib 
          -Wl,-R/usr/X11R6/lib -Wl,-soname -Wl,libGL.so.1
          -o .libs/libGL.so.1.0.5
          -I/disk/disk0/pkgsrc/graphics/MesaLib/work/.buildlink/include
          -lX11 -lXext -lm

The problem appears to be that work/.buildlink/lib/libX11* doesn't
exist, although lots of other X libs are linked therein. (Same in
work/.x11-buildlink/lib...)

No idea why.

>How-To-Repeat:

bmake, given suitable install.

>Fix:

No idea.
