What problems (besides no support in portmaster) can arise due to
parallel use of Python 2 and Python 3 in the same FreeBSD system? I
see none: the resulting packages (python{26,31}-* and py{26,31}-*)
install files in different locations (they use e.g.
/usr/local/lib/python2.6 vs /usr/local/lib/python3.1). Moreover;
during the current stage of the Python's development there are
legitimate reasons for using Python 2 for some projects and Python 3
for the rest ( http://wiki.python.org/moin/Python2orPython3 ). And I
don't
expect that this situation will change soon (changes in Python 3 are
rather essential, so many packages will stay Python2-only for some
time)...
Well, as for me - it's not difficult to manage python2/3 packages
using just plain ports infrastructure. Thanks for explanation!
