I could just be being dumb here but it doesn't seem like it would. The python(abi) will require a specific major.minor of the python package itself. It will not require a python-setuptools (for instance) that was built for the same version of python as the package you are installing. If it was true, then you wouldn't need the separate python2dist and python3dist as python(abi) would take care of the difference between packages built for python2 and python3.</p><p dir="ltr"><br></p><p>example autogenerated deps:</p><p>python-setuptools</p><p> Provides: python2dist(setuptools)</p><p> Requires: python(abi) = 2.7</p><p>python2.6-setuptools</p><p> Provides: python2dist(setuptools)</p><p> Requires: python(abi) = 2.6</p><p>python2.6-foo</p><p> Requires: python2dist(setuptools)</p><p> Requires: python(abi) = 2.6</p><p><br></p><p>On my system, I have installed, python-2.7.0 (which provides python(abi)==2.7), python2.6-2.6.0 (which provides python(abi)==2.6), and python-setuptools (deps listed above).

Thus, the library will not function correctly because python-2.6 will not be able to import setuptools.</p><p><br></p><p>-Toshio<br></p><p><br></p><p><br></p>
