Fails to build on Travis (Ubuntu 14.04)

Created by: yookoala

The last successful Travis build of pycangjie was with Ubuntu 12.04. Travis has been moved to use Ubuntu 14.04 as base image. The version number of cython was bumped to an embarrassing "0.20.1post0", which is not a number.

That's why you cannot correctly run the autogen.sh. You'd get an error like this.

ValueError: invalid version number '0.20.1post0'
configure: error: Please use cython >= 0.14

I recently tried to build it on Travis with basically the same test script. The build was failed with this error. The full autogen.sh output is like this:

automake: At least a source file is in a subdirectory, but the 'subdir-objects'
automake: automake option hasn't been enabled.  For now, the corresponding output
automake: object file(s) will be placed in the top-level directory.  However,
automake: this behaviour will change in future Automake versions: they will

automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.
