Hi, We're running into travis-ci time limits when building OSX wheels: https://travis-ci.org/MacPython/scipy-wheels/builds/204105101 The main reason for this is that, for OSX, we are building twice, first for i386, then for x86_64, and then combining these builds into a 'fat' binary to be compatible with either architecture. The builds take a long time, hence the timeout. I believe that the i386 architecture on OSX is pretty much unused now. For example, it looks like south of 0.5% of CPUs running OSX cannot do 64-bit: https://www.adium.im/sparkle/#cpu64bit I propose that we drop the i386 part of the scipy build, but continue to distribute apparently dual-arch wheels (architecture 'intel') so that the wheel installs into the Python.org and System Python builds [1]. This has the added advantage of making the wheel build process a lot simpler. Thoughts? Best, Matthew [1] https://bitbucket.org/pygame/pygame/issues/300/os-x-wheels-dmg-and-zip-build...
