How to install some software that requires Python 2.6 and rejects 2.7?

[Fernando Cassia]

Hi there,

I'm running F17 Beta (RC3) x86.

I'm trying to install the Scribes editor
http://scribes.sourceforge.net/features.html

of which http://mcepl.fedorapeople.org/rpms/ maintains Fedora RPMs for here
http://mcepl.fedorapeople.org/rpms/scribes-0.4-0.bzr20111117r1032.1.el6.noarch.rpm

However when I try to install it I get:

---
rror: Package: scribes-0.4-0.bzr20111117r1032.1.el6.noarch
(/scribes-0.4-0.bzr20111117r1032.1.el6.noarch)
           Requires: python(abi) = 2.6
           Installed: python-2.7.2-18.fc17.i686 (@koji-override-0/$releasever)
               python(abi) = 2.7
               python(abi) = 2.7
           Available: python3-3.2.2-12.fc17.i686 (fedora)
               python(abi) = 3.2
 You could try using --skip-broken to work around the problem
** Found 1 pre-existing rpmdb problem(s), 'yum check' output follows:
nspr-4.9-2.fc17.i686 is a duplicate with nspr-4.9-1.fc17.i686

Of course, skip-broken doesn't help.
Any ideas on how to proceed?

TIA..
