you won't believe this one weird fix
    
    For some strange reason, on EL6 the autosetup macro expands in a way
    that runs the patch command into the next line.  In this case, it was
    resulting in `/usr/bin/patch -p1 -sfind -name '*.py'` being run and
    failing.  It works fine everywhere else, but I might as well keep the
    spec file identical between branches since the fix is so simple.
