Hi Akhil,

You sent this to the list a while back, but no one seemed to
reply, so I thought I'd take a stab at it.

I'm not sure about the first problem you mentioned, but the
second one I think I can shed some light on. You would get this
if /Users/ashah/.matplotlib is owned by root, your IPython error
may also be related to this. The output of

  $ ls -al ~/ | grep matplotlib

should be something like:

drwxr-xr-x   3 ashah   ashah       4096 2010-12-20 17:58 .matplotlib/

not:

drwxr-xr-x   3 root   root       4096 2010-12-20 17:58 .matplotlib/

you can use something like this command to fix the above
  $ chown ashah:ashah ~/.matplotlib

best,
