I can't quite remember what I was doing using --with-GL option !?  I think the "./configure" was failing so I started mucking around with it (I misunderstood the purpose of this option I think) ... and your right ... I don't need it (but I can't confirm this now as I'm at work).

As you point out it seems to be failing on expecting pthread linkage.

So do I need to add -lpthread to the ./configure script or something ???  Or should I be tracking down a version of Mesa with pthread pre-linked ?

Thanks for your help on this.
