How to package .pyc files

[Gleb Popov]

Hello. I'm fiddling with the devel/mercurial port (
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=242463 ). The current
Makefile results in

Error: Orphaned: %%PYTHON_SITELIBDIR%%/mercurial/__modulepolicy__.py
Error: Orphaned:
%%PYTHON_SITELIBDIR%%/mercurial/__pycache__/__modulepolicy__.cpython-37.opt-1.pyc
Error: Orphaned:
%%PYTHON_SITELIBDIR%%/mercurial/__pycache__/__modulepolicy__.cpython-37.pyc

errors. However, adding these files into pkg-plist seems a bit hard - it
requires %%PYTHON_VER%% subst and a special treatment for python2 case.
Which made me wonder - should these files be packaged at all? If yes, maybe
there is some simple solution I'm missing?

Thanks in advance.
