This is also the case on linux.

I think the "solution" here is to stop linking OSMesa against GL and
instead just pull in libmesa and friends all the time. In addition to
avoiding the symbol visibility issues, it makes OSMesa more
standalone, which is what people want anyway.

I have a patch I was working on but haven't tested. I'll try to wrap
it up tonight and shoot it over to you for a test. I'm attaching what
I have right now if you want to play around with it.
