I think that's getting a bit too convoluted and the whole approach is too
fragile. Recalling that the original purpose--still required--of the segment
was to make sure that libxml2's python module got put in the right
$PREFIX/lib/pythonxx, none of that will work if the user does
jhbuild build python3
jhbuild meta-gtk-osx-bootstrap
Xcode 12's addition of a python3 framework that doesn't include the headers is
another problem because pipenv is finding it and setting up the virtenv in
spite of the directive in Pipfile to use 3.10 which is supposed to trigger an
automatic build and install of python3.10 and create a virtenv from that. As
long as one builds and installs python3 into $PREFIX it's not that important,
but if one doesn't then building libxml2 and pygments will fail for no Python.h.
To add to the fun I discovered yesterday that librsvg has added two more PyPi
dependencies, documents and go-documentation, in their master branch, and no
configure option to disable making documentation and thus to avoid them.
It would be nice to have a pip3 module in jhbuild so one could just say
<moduleset>
<pip3 id="pygments"/>
</moduleset>
and it would do the right thing. That still wouldn't fix libxml2 but it would
take care of everything else.
Failing that we need logic in jhbuildrc that looks at the project modules list
to see what jhbuild is actually going to build and checks for
$PREFIX/bin/python3-config to see if python3 is already built. Easiest said
than done, unfortunately.
