The python311 configure script doesn't look for the headers, though,
but it looks for libnsl and libtirpc pkgconfig modules. This assumes a
glibc (Linux) system, where that functionality got split out of the C
library into these modules.

Hence, the header check in the Makefile is out of sync with what the
build actually does.

I have a temporary hack for that on my Linux box, which would result in
PLIST.nis=no on your system.

We discussed that some days ago … it was recommended to me to create a
libnsl package with doing some magic.

Anyhow, that is my current hack. I am not sure if I'd be the first
doing some proper solution, as I am trying to fix up the NumPy build
regarding BLAS usage and python311 PLIST trouble is a nuisance in
