hi Marcus,
you are correct on most counts.
it's the make in ports that's problematic.
- no problem in installing all/any version of lang/python.
- the issue is with 3rd. party modules, and more specifically
when installing. Furthermore, most modules compile for all
versions of python, but installing them is the issue:
- if the module is installed, no matter what python
version, it will be deinstalled - unless FORCE_PKG_REGISTER=,
which prevents the deinstall issue
IMHO, the check for is installed does not correctly use PYTHON_VERSION
example:
/usr/local/bin/python -> python3.3
# cd /usr/ports/devel/py-setproctitle
# make install
===> Installing for py33-setproctitle-1.1.7
===> py33-setproctitle-1.1.7 depends on file: /usr/local/bin/python3.3 -
found
===> Generating temporary packing list
===> Checking if devel/py-setproctitle already installed
===> py33-setproctitle-1.1.7 is already installed <==== NOT TRUE
You may wish to ``make deinstall'' and install this port again
by ``make reinstall'' to upgrade it properly.
If you really wish to overwrite the old port of devel/py-setproctitle
without deleting it first, set the variable "FORCE_PKG_REGISTER"
in your environment or the "make install" command line.
*** [check-already-installed] Error code 1

- somehwere it should be mentioned:
- how to set the default python
i.e: usr/local/bin/python is a symlink, as is python-config
- the bsd.python.mk is very confusing, and has some errors
at the moment my goal is to have python 2.7 as default, and 3.2/3.3
as optional, and using PYTHON_VERSION= and FORCE_PKG_REGISTER= ie:
make PYTHON_VERSION=3.3 FORCE_PKG_REGISTER= clean install
is a workaround
