#65903: python ports: inadvertent conflicts, due to files installed to
${python.prefix}: LICENSE, etc

 Priority:  Normal   |  Milestone:
Component:  ports    |    Version:  2.7.2
 Keywords:           |       Port:  py-about-time py-pytest-datadir
---------------------+---------------------------------------------
 Trying to install a smattering of Python ports - including those under the
 umbrella of `py-pytest-xxx` - fails due to port-specific files installed
 directly in `${python.prefix}`.

 For example, `py-about-time` is one example:

 {{{
 $ port provides
 /opt/local/Library/Frameworks/Python.framework/Versions/3.10/LICENSE
 /opt/local/Library/Frameworks/Python.framework/Versions/3.10/LICENSE is
 provided by: py310-about-time
 }}}

 Along with `py-pytest-datadir` (after first deactivating `py310-about-
 time`, to allow activation):

 {{{
 $ port provides
 /opt/local/Library/Frameworks/Python.framework/Versions/3.10/LICENSE
 /opt/local/Library/Frameworks/Python.framework/Versions/3.10/LICENSE is
 provided by: py310-pytest-datadir
 }}}

 Rather than placing the full onus on maintainers, though, we should check
 for this in pg `python`. And cause the install to fail, if any such files
 are found.
