I did the same thing. Out of 19 packages to be deleted here are the
four that matter. I believe the rest are mainly dependencies for these
four.
asterisk16: 16.9.0
freeradius3: 3.0.20
lilypond: 2.18.2_10
mailman: 2.1.29_6
I was surprised to find Asterisk in that list. It appears to be due to
a dependency on net-snmp. I am rebuilding with Python bindings removed
from the config. If net-smtp can't be build with 3.x then the option
should probably be removed.
I rebuilt freeradius3 which pulled in Python2.7. I then removed
python27 and it did not remove freeradius3. I then modified the
Makefile to change PYTHON_USES to 2.7 and it built fine. I have no way
to test if it works yet.
I tried building lilypond with python2.7 removed from USES but its
configure script failed due to Python < 3.0. I couldn't find any
discussion about upgrading the version of Python but WikipediA says that
it has 120,000 lines Python code. As far as I can tell there is nothing
as good as Lilypond for engraving music. It would be quite a blow to
musicians if that was removed.
As for mailman, it looks like we only need to upgrade to a current
version. The site says that 3.x uses Python 3. Requires it in fact.
