My rationale for removing the --prefix argument was that a user might want
to compile matplotlib from source on MacOSX instead of install it from a
package (assuming such a package exists). As it stands now, the make.osx
file has some configuration at the top and then states that you shouldn't
need to configure past a point.
I've recently gone from relying on Enthought to compiling the packages I use
from source. All of the other packages (numpy/scipy, ipython, PIL, pyserial)
install by default on the site-packages relevant to the python version used
in the install. Removing the --prefix argument would bring the same
functionality to matplotlib on OSX. This default could be modified by
developers that would rather install in a test environment.
As I mention in the pull request, though, I'm still unsure if the
dependencies are compile-time or not. I've left the PREFIX intact after
installing into the production site-packages and I haven't had any issues so
far. The reason the PREFIX is needed, as README.osx explains, is because OSX
can have different types of zlib, png and freetype installed on the system.
If this change blocks the pull request from going through, though, I could
just revert that change and open up another one once we've cleared up any
doubts about what the rationale for having the --prefix in the first place
are.
