Pynac problem with Big Sur

[dwb...@gmail.com]

Last week I was able to build sage, and the documentation on Big Sur (MacOS 11.2.1) after the fixes in Trac tickets #31183 and #31344.

There was another update to Xcode last week. When I first went to rebuild sage, it failed building cython. I updated homebrew and then I was able to build cython but now it fails building pynac with the message unable to find gmp.h.

I do have gmp installed with homebrew.

I am attaching the pynac log.

I am unable to reproduce this (on macOS 11.2.1 with latest xcode and homebrew)

Did you do

source .homebrew-build-env

before starting rebuild? (this command needs to be run once in each
terminal session/tab)

If yes, do you have /usr/local/include/gmp.h ?

Thank you, after that I was able to build sage.
