matplotlib upgrade 0.52->0.53.1

Hi,

  I finally tried to upgrade from matplotlib-0.52 to 0.53.1.

When i try to run my app that works fine on 0.52,
it crashes when i try to make plot (the matplotlib part).

This may not be enough info for you to help me,
but on the other hand you might immediately see something
that i have wrong. ...err is there the equivalent of
a 'make clean" in the "python setup.py install"
(yup i'm a newbie to some aspects of python)

...i just tried a re-install of 0.52..and
while it did stuff, clearly 0.53 is still being used.
It's my home machine...so not a real big deal.
I also tried:

[root@...173... matplotlib-0.52]# python setup.py clean
running clean
[root@...173... matplotlib-0.52]# python setup.py install
running install
running build
running build_py
running build_scripts
running install_lib
running install_scripts
changing mode of /usr/local/bin/postinstall.py to 755
running install_data
[root@...173... matplotlib-0.52]#

and

[root@...173... matplotlib-0.53.1]# python setup.py clean
running clean
removing 'build/temp.linux-i686-2.3' (and everything under it)
[root@...173... matplotlib-0.53.1]#

and then:

[root@...173... matplotlib-0.52]# python setup.py install
running install
running build
running build_py
running build_scripts
running install_lib
running install_scripts
changing mode of /usr/local/bin/postinstall.py to 755
running install_data
[root@...173... matplotlib-0.52]#

I also tried moving the 0.52 dist to a back, untarring and then
redoing the "python setup.py install"

...but still i'm stuck with my non-working upgrade.

ok..so i went into floyd:/usr/local/lib/python2.3/site-packages>
and moved the matplotlib dir to matplotlib.bak and then tried
a re-install of 0.52...my app again words..whew! (is there an
easier way to uninstall?)

Thanks for any comments (including RT_Fine_M section xx),

The same trick should (hopefully) get 0.53.1 to work: get rid of the old matplotlib in site-packages before installing a new one. Probably some files from 0.52 are screwing up 0.53.1.

(This is a limitation of Python's distutils -- upgrades should really wipe the package out of site-packages rather than adding files.)

Cheers!

...and also a limitation of my late night thinking.
Your suggestion appears to have worked like a charm.
I'll definitely use your advice for all future upgrades of
any python packages.

Thanks!!

Jim
