Python27 has Linking issues with Xcode 11.1 and MacOS Catalina 10.15

[IComplainInComments]

Python27 fails to stage into the destroot. After looking through the logs its seems ld is missing symbols for the x86_64 arch ld: symbol(s) not found for architecture x86_64 . Building after port cleaning, and rebuilding without cleaning gives the same result.

Here is a log snippet of where it gets funky

python27 build log

The Milestone field is for use by Macports team members only, please do not set it.

Any idea if this has been reported upstream?

For Python? Looking on the github and python ticket tracker, no.

[jmroot (Joshua Root)]

I'm not able to reproduce this. Why are you using the 10.14 SDK on 10.15?

For the love of GOD! Why is xcode on 10.14 SDK? Let me switch to 10.15, and ill let you know if it fixes it...

[jmroot (Joshua Root)]

OK, thanks for the confirmation.
