 From what I understand (this is according to folks at Red Hat, so take 
it w/a grain of salt), most applications that broke when Red Hat 
implemented NPTL broke because they were not properly written. Examples 
of 3rd-party applications not working w/NPTL carry very little weight 
with Red Hat. I'm not saying there aren't problems, but everything 
included in the distro, and the vast majority of 3rd-party packages 
I've used work just fine w/NPTL. There are always a few things that 
don't work right from distro to distro, version to version.

Compiling from source definitely works, but it will likely cause 
problems if you try to upgrade to Fedora Core in a few days here... 
Also see Axel's reply.
