Re: MacOS 26 build problem

I ignored/missed your question in your first reply.

I did not set LDFLAGS.  However, after checking with ‘env’, I see it is set, and includes that pesky definition.  I can’t be sure, but my only guess now is that it comes from building Sage with the new conda/mamba scheme.

In any case, I reran the build, and it succeeded.

I’ll try out 2.18.1 alpha tomorrow.

Thanks for tracking that down!
