spice-server: configure: no module named 'six'

spice-server fails to configure:

Program python3 found: YES (/opt/local/Library/Frameworks/Python.framework/Versions/3.11/bin/python3.11)

subprojects/spice-common/meson.build:141:6: ERROR: Problem encountered: Python module six not found

The Portfile has py_ver_nodot=310, and has a depends_build on py310-six, but it is actually running Python 3.11 during the configure.

I don't know why it chose Python 3.11. My port select for python3 is "none".

If I switch py_ver_nodot=311, it configures after it installs py311-six.

(But, it fails later with ":info:build asciidoc: ERROR: manual.txt: line 9: only book doctypes can contain level 0 sections", but might be the subject of another ticket)

So, the Portfile tries to depend on py${py_ver_nodot}-six, but the configure appears to be picking some version besides python${py_ver_nodot} for its execution.

have you “sudo port selected” python311 as your python3?

[jmroot (Joshua Root)]

The port doesn't actually tell the build system which python to use, so I guess it just picks the latest.

[jmroot (Joshua Root)]

So meson apparently has no built-in support for choosing which python to use via an environment variable or command line option. Does this work for you?

See: #66535

[jmroot (Joshua Root)]

Nope. Have to define the option manually apparently.

OK, fails on older platforms still, but that's a different issue.
