their previously installed Pythons.
Wouldn't it be better to use '--with-framework-name', IIRC I
introduced that in 2.6:
./configure --enable-framework --with-framework-name=EPD
This will create a framework named 'EPD.framework' instead of
'Python.framework'.
(I also work for Enthought)
EPD is still using Python 2.5 as its base, though we expect to be on
2.6 shortly.
I'm not clear on what the name of the framework effects. Would you be
able to install pre-built binary distributions, built against an "EPD"
framework, into a "Python" framework? And vice-versa? If not, then
this probably isn't a usable solution for us.
Extensions are not linked to the framework, extensions build for a
Python.framework should therefore work unchanged in a EPD.framework.
That said, I haven't checked yet if 3th party tools work with a renamed
Python framework, I know that py2app hardcodes the name Python.framework
and IIRC virtualenv does the same.
Both could and should be changed, and that's something on my todo list
for various reasons. One of which is that I want to have side-by-side
installs of a couple of build variations of Python on my machine.
It would be great to see more support for alternative framework names. It would
be a much better alternative. There are also other packages, primary non-Python
ones like VTK, that still expect Python.framework. With enough effort, I assume
we can make them work, though. At the time we did this, the version number
change seemed like an easier alternative. It tends to only generate a couple of
"WTF?" moments rather than real problems, and we are the ones who usually get
the support emails.
