>Description:
On recent ports tree (r332163) and CURRENT10/11, I receive error message shown below when recompiling graphics/GL and graphics/GLU:

It seems, the mentione file isn't present and following the instruction in section solving makes the ports installable, again.

>How-To-Repeat:

>Fix:
touch /usr/ports/graphics/libGL/work/.metadir/+INSTALL
portmaster -C graphics/GL graphics/GLU
