It looked that way to me as well.

Don't really know enough about this to even comment.

Yes. That and X11. But the only reason I emailed this list is that the exact
same package has worked severel times before. In fact, it worked several times
the same day before it gave up. I am not saying that it is gcc. On the other
hand, gcc is the one that errors and I was hoping someone who knew enough about
it could point me to the real problem.

I believe due to the problems with gcc not being able to find X11 or qt that
there might be a problem with the linker or maybe ldconfig. I believe the
problem might be related to the running of ldconfig to add a lib path
(something I have done several times before without problems).

At any rate, can you give me a clue as to where the real problem might reside?
