Just trying to build the latest release on a stable Gentoo amd64 box and got this: parti-all-0.0.6/wimpiggy/lowlevel/wimpiggy.lowlevel.bindings.pyx:114:10: Expected an identifier or literal Upgrading pyrex from 0.9.4.1 (stable) to 0.9.8.5 (testing) fixed it. It may be worth adding a version test for pyrex? Cheers Antoine
