G'day,

There exists a conflict between the aalib vs. aalib-x11 library when
building gphoto2 with aalib-x11 package installed as they are mutually
exclusive. Building gphoto2 with the aalib-x11 package installed will
cause a runtime error due to missing path to the X11 libraries.

gphoto2 will build and run fine with both aalib-x11 and aalib. Currently,
the build process will fail if the aalib-x11 package is required and
installed by another package. There are only 3 packages that make use
of the aalib* libraries - namely,

	devel/SDL		- aalib-x11
	graphics/aview		- aalib-x11
	graphics/gphoto2 	- aalib

One possible solution to this problem is to let gphoto2 probe
for the aalib package, autoconfigure and include the correct
buildlink.mk files - see patch below:

The alternative is to have aalib probe for X11 and autoconfigure
itself to either include or exclude X11 support.

Any comments?

Many thanks in advance
