Single generic package for python 2.x

[Raphaël De GIUSTI]

I have a python application, it can run on Python >= 2.6 and it's
architecture independant.
I need the rpm package of this application to be installed on Fedora 14
(python 2.7) and Centos 6.2 (python 2.6).
I currently use mock to build one rpm package for each "flavour" and it
works well.

Do I really have to use mock and build 2 rpms or is there another way to
create a single generic python 2.x rpm package ?

Because apparently I can't install the Centos compiled rpm on Fedora.
It gives me this error message :

**************************************************************
error: Failed dependencies:
python(abi) = 2.6 is needed by myapp-0.9.el6.noarch
**************************************************************

Here is the relevant part of my .spec file :

distutils.sysconfig import get_python_lib; print(get_python_lib())")}

distutils.sysconfig import get_python_lib; print(get_python_lib(1))")}
