This is clearly a duplicate of 959, I am keeping 959 since it has a much clear bug title.

I am working on a fix currently to add virtual/libgl to the DEPENDS, need to verify this will work for machines without a libgl (mesa) implementation correctly.

*** This bug has been marked as a duplicate of bug 959 ***

From autobuilder newest build logs, no such error happened.

verified on qemuppc nightly build 20110412-1:
