>Description:
	Building some ports as user (into my home) which generally
	works fine, I just ran into the following with graphics/libGL:
:
python u_format_access.py u_format.csv > u_format_access.c
python u_format_table.py u_format.csv > u_format_table.c
python: not found
python: not found
gmake[4]: *** No rule to make target `u_format_access.c', needed by `depend'.  Stop.
gmake[4]: Leaving directory `/scratch/tmp/gerald/shscratch/tmp/gerald/ports.svn/graphics/libGL/work/Mesa-7.6.1/src/gallium/auxiliary/util'
gmake[3]: *** [default] Error 1
gmake[3]: Leaving directory `/scratch/tmp/gerald/shscratch/tmp/gerald/ports.svn/graphics/libGL/work/Mesa-7.6.1/src/gallium/auxiliary'
gmake[2]: *** [default] Error 1
gmake[2]: Leaving directory `/scratch/tmp/gerald/shscratch/tmp/gerald/ports.svn/graphics/libGL/work/Mesa-7.6.1/src/gallium'
gmake[1]: *** [subdirs] Error 1
gmake[1]: Leaving directory `/scratch/tmp/gerald/shscratch/tmp/gerald/ports.svn/graphics/libGL/work/Mesa-7.6.1/src'
gmake: *** [default] Error 1

Stop in /shscratch/tmp/gerald/ports.svn/graphics/libGL.

	It appears graphics/libGL depends on an executable named
	"python", but does not seem to have any dependency on that
	or Python as such?

>How-To-Repeat:
	
>Fix:
	Add dependency / USE_PYTHON ?
