Running the testsuite (SAGE_CHECK) fails with

[gmpy2-2.2.1] [spkg-check] python3: can't open file '/Users/buildbot-sage/worker/sage_git/build/local/var/lib/sage/venv-python3.12.5/var/tmp/sage/build/gmpy2-2.2.1/src/test/runtests.py': [Errno 2] No such file or directory

Presumably the entrypoint moved in the new version

Presumably the entrypoint moved in the new version

yes, this is the case, sorry for not checking. Fixed now

[dimpase]

OK now?

This test now tries to download stuff from the internet (the CI tests with poisoned proxy environment variables):

@vbraun - this looks pretty wild to me that this PR does trigger this, are you sure it's not something else in your branch?

[vbraun]

Yes, quite certain. I built with and without this PR. Took quite some time to track down...

[dimpase]

@vbraum This might be due to hypothesis being bumped to standard without the usual tarball/checksums dance, simply by changing the package type: so the network access you notice is an attempt to install it from the net, delayed.
