Helpful to understand the issues. It's interesting to me that I've been following the distutils-sig for a good while, and hadn't seen any of this. I suspect one of hold-ups for wheel is the scattered conversation. Though I see Nick on that thread, so that's good.<div>

<div>The warning is still correct, and I still recommend that all OS X users easy_install (not pip) readline. The issue has been discussed in various places (<a href="http://mail.scipy.org/pipermail/ipython-user/2011-September/008426.html" target="_blank">here is one</a>), but it's a sys.path priority issue. Nobody should ever use pip to install readline. But since people still do, incorrectly believing that pip is actually a replacement for easy_install,</div>

But it's a lot more delicate to be sure that the eggs actually self-identify correctly, and will be properly ignored on systems where they won't work. This is why IPython has decided against building (official) wheel bdists for at least another release.</div>
</div></div></blockquote><div><br></div><div>There has been a lot of discussion about this on the distutils list, and I _think_ there is more or less a consensus that we should put binary wheels up on PyPi for the <a href="http://python.org/">python.org</a> builds for Windows and OS-X. Those should work at this point (sse issues asside for numpy/scipy)<br>
<br></div><div>Doing it for Macports or HomeBrew, or what have you is pretty much alost cause, but that's not a big deal -- those are systems designed for people to compile there own stuff anyway. similar for Linux.<br>

<div>I am 100% behind a semi-not-so-official-wheels-for-osx effort a la Gohlke, that's actually why I started publishing <a href="http://kerbin.bic.berkeley.edu/wheelhouse/" target="_blank">my own wheels</a>. </div></div>
