It is probably an addition dep (optional) that is being detected on your 
system and causing the failure.  Personally, I would build in a chroot 
and ignore the issue.  There are plenty of packages that should only be 
built in a chroot due to issues similar to this and _ALL_ packages 
should be built in one anyway.
