In the main branch, pyperformance fails to build due to something regarding the freeze module:

The performance server has been failing from some time due to this problem :(

I think that I just fixed it with:

commit 41551ee7e24fb6c58846836d3655dbb212281206 (HEAD -> main, upstream/main)
Author: Victor Stinner <vstinner@python.org>
Date:   Fri Sep 17 20:20:43 2021 +0200

    bpo-45020: Fix build out of source tree (GH-28410)
    
    * Makefile.pre.in: Add $(srcdir) when needed, remove it when it was
      used by mistake.
    * freeze_modules.py tool uses ./Programs/_freeze_module if the
      executable doesn't exist in the source tree.

I have checked and indeed this has been fixed already.

Thanks a lot, Victor for the fix!
