I wanted to set up a python27 + spyder IDE environment in SL65. I also
wanted to control this environment so I could set up another for python33 in
the future.

This is what I did:

Install python27 with yum from softwarecollections repo:
http://ftp.scientificlinux.org/linux/scientific/6.4/x86_64/external_products/softwarecollections/
That installed python27 in opt/rh/root/...

Then I wanted to enable pip and then install spyder IDE. spyder IDE needs
qtwebkit and PyQt4-webkit. So I used yum again but it installed those
packages for system python instead of python27. So the spyder IDE fails to
launch because it misses PyQt4.

Please provide me with some clues in order to set up this environment (I
might start from scratch) without messing everything from the beginning.
Thank you.
