Description of problem:
Attempting to build the SRPM of libimobiledevice fails with
Error: Cython version >= 0.13.0 is required.  You have Cython version 0.16.  You should look at http://www.cython.org

Version-Release number of selected component (if applicable):
Cython-0.16-1.fc17.x86_64
libimobiledevice-1.1.4-1.fc17.x86_64

How reproducible:
Always, with the above packages. The previous release of Cython, Cython.x86_64 0:0.15.1-2.fc17, works

Additional info:
There's an upstream bug entry for this for libimobiledevice: http://libiphone.lighthouseapp.com/projects/27916/tickets/264-error-compiling-with-cython-016_rc0

The problem is an error in parsing the version string for Cython. It fails on versions that are not in the form ##.##.## . A patch is available at http://cgit.sukimashita.com/libimobiledevice.git/commit/?id=70dfe8ad1766990386f1db04bbe5a4826bcde4e5

This patch resolves the version number error, but the package still fails to compile:
