Hello there, I've got some problem during update of ports. 
I excluded (libGL)port by this command :
I have the same problem in FreeBSD 10 now with mesa with "intel" (i915 i965 r200) driver compile process in dri.
Thanks.

			I excluded (libGL)port by this command :
 portmaster -a -x=graphics/libGL, and it's not excluded exactly!I have the same problem in FreeBSD 10 now with mesa with "intel" (i915 i965 r200) driver compile process in dri.
Thanks.
 #portmaster libGL
