problem in graphics/libGLU

libGLU-7.0 does not install properly on my system. there seem to be two
problems:

1. Mesa-7.0/bin/mklib does not know how to resolve '-lGL'
2. Mesa-7.0/bin/mklib does not return a status of failure so the port
tries to install and fails

adding '-L/usr/local/lib' to the ../../../bin/mklib -o GLU -linker 'c++' 
-major 1 -minor [...]
command in Mesa-7.0/src/glu/sgi/ solves the first problem so an appropriate
LIBDIRS variable in the port skeleton Makefile should fix complaint 1)

i do not know enough about the port to know if it's feasible or desirable
to fix 2)

thank you
