well drat. I had hoped they would deprecate older Python versions with a major release (e.g., 1.20 -> 1.21) not a minor one such as this. I'll fix it up shortly.

[michaelld (Michael Dickens)]

Just noticed that it was a major release upgrade ... I had just forgotten to push the prior 1.20 release ... oops! :)

While this might be moot if we downgrade the version, it's still worth a mention: I'm now seeing build failures for multiple py-numpy subports (including both 3.7 and 3.8), with the following:

CCompilerOpt.feature_test[1458] : testing failed

This is occurring on macOS 10.12. Based on a quick look at the port build history, the same failure is also occurring on our builder:

Thanks for that update @macsguy ... I'm working to fix the immediate issue; then I can look into the next issue.

In aff2ee944f3e34f9662d15bebb0f6ed89bd08efa/macports-ports (master):

py-numpy: cap py36 at 1.19.X and redo patches per capped version

Closes: #62243

[michaelld (Michael Dickens)]

@macsguy : I doubt my changes will fix the issue you're noting. If it persists, can you please open a new ticket here with updated info? I can boot one of my OSX build systems into 10.12 for testing / evaluation / debugging. Thx!
