The rebuild is necessary because libffi was upgraded. /opt/local/bin/python point indeed to Python version 3.8.5 which has problems with the test.

Main.log from PPC Leopard

[ballapete (Peter "Pete" Dyballa)]

Selecting python27 lets the configure step pass. llvm-3.4 @3.4.2_13 (active) platform='darwin 9' archs='ppc' date='2020-09-17T13:01:16+0200' obviously can be built with Python 3.8.5.

[ballapete (Peter "Pete" Dyballa)]

In llvm-3.4 the configure ckeck for Python is simply patched away – wouldn't this work for llvm-3.3 as well? (llvm-3.3's configure script has on lines # 1990 and 1991 bugs: The lines should start with ": ".)

[ballapete (Peter "Pete" Dyballa)]

The attached patch should resolve the problems – not tested yet because port is rebuilding other ports… (Maybe on the weekend!)

Proposed patch to work with any of MacPorts' Python versions on old Macs (and solve reports about a '-pipe' command that does not exist)

thanks for the info and patch, Peter.This turns out to be a duplicate of #61172.

Replying to kencu:

This turns out to be a duplicate of #61172.

I've seen this report but assumed it was about a variant…

Main.log from Catalina with Python 3.8.5 – failure

[ballapete (Peter "Pete" Dyballa)]

Tested this patch on Catalina with Python 3.8.5: failure. Selecting python27-apple as python lead to success. (make check seems to have been successful too.) Selecting python38 for python again and adding --with-python=${prefix}/bin/python2.7 to configure.args lead to the same failure as before – because there was no code to handle this additional configure argument. Not applying my patch lead to success again – in the presence of the additional configure argument --with-python=${prefix}/bin/python2.7. (make check seems to have been successful too.)

The best effort should be to add a dependency to python27 and add --with-python=${prefix}/bin/python2.7 as an unconditional configure argument.

Thanks! I'll incorporate that into some patches soon. Appreciate your input.
