Description Chris Hutchinson 2019-12-11 01:30:43 UTC 
I spent all day yesterday on a fresh world/kernel
fighting to install ports -- most of which failed
to build due to python (version) related errors.
I finally blew everything off the disk, and built/
installed a new world/kernel today, and made another
attempt, which (of course) also failed.

Procedure:
make/install perl5.30, python27 && python37.
cd /usr/ports/x11/xorg; make config-recursive until
the dialogs will no longer appear.
make

This is the result:
===>  Staging for xorg-7.7_3
===>   xorg-7.7_3 depends on file: /usr/local/libdata/pkgconfig/dri.pc - not found
===>   mesa-dri-18.3.2_9 depends on package: wayland-protocols>=1.8 - found
===>   mesa-dri-18.3.2_9 depends on file: /usr/local/libdata/pkgconfig/pthread-stubs.pc - found
===>   mesa-dri-18.3.2_9 depends on executable: bison - found
===>   mesa-dri-18.3.2_9 depends on executable: msgfmt - found
===>   mesa-dri-18.3.2_9 depends on executable: gmake - found
===>   mesa-dri-18.3.2_9 depends on package: pkgconf>=1.3.0_1 - found
===>   mesa-dri-18.3.2_9 depends on file: /usr/local/bin/python2.7 - found
===>   mesa-dri-18.3.2_9 depends on package: llvm80>=3.9.0_4 - not found
===>  llvm80-8.0.1_3 needs Python 3.6 at least, but 2.7 was specified.
*** Error code 1

These (python) related errors were the only ones generated all day
yesterday. As a result; most nothing can be installed when more
than one version of python is installed.
It is clear that python multiplicity is no longer supported.
Someone forgot to mention that in UPDATING. Please make an entry
ASAP so others will not have to suffer needlessly.

Multiple lang/python* ports can be concurrently installed. 

The error described here is an issue related to a specific subset of dependency combinations, see bug 237795 comment 6, and not related to concurrent installation of multiple python versions.
