Are you deliberately misreading me? I wasn't saying anything about you
supporting pkgsrc. I was explaining what "third party" means in this
context, and why it is that we try to make our libc support everything

Then why are you comparing "pth" to the job of making a kernel
assisted pthreads system work? They are unrelated.

I give up. If you think you can make NPTL somehow work on an operating
system that doesn't have the kernel support for it, well, good luck to
For the record, if anyone OTHER than Robert is interested in
discussing various things that NetBSD could do to make it easier for
people to use our stuff with Debian, please get in touch with
me. We're always interested in making improvements to our available
