Crypto 2.4 install via setuptools dies re: missing config.h

[bitprophet]

I am unable to get PyCrypto 2.4 to install on any of my target systems via easy_install, or via dependent projects' setup.py files. Using pip works fine. PyCrypto 2.3 also installs fine in the same situations.

I have documented my findings in [this Fabric ticket](https://github.com/fabric/fabric/issues/459).

For now I've had to update software I control to specify PyCrypto >=2.1, <2.4 to protect some segment of my userbase from encountering this bug.

I'd like to add that using zc.buildout's zc.recipe.egg break while installing pycrypto = 2.4

There is no easy way to modify egg build process to call ./configure before building pycrypto, even in zc.recipe.egg:custom mode.

For now I pinned pycrypto to 2.3

I don't know anything about zc.buildout. How is it invoking setup.py?

Also, if anyone knows, why doesn't bdist_egg invoke the "build" task before doing whatever it does? Is there any documentation about the interface between these various tools and setup.py? I don't want to have to reverse engineer setuptools, distutils, distribute, etc. just to invoke a configure script.

Same with virtualenv:

The same problem I guess:

This is fixed in PyCrypto v2.4.1

[bitprophet (jeff-bitprophet)]

Fix confirmed for me on OS X 10.7, Python 2.7, multiple dependent projects. Thank you!

Fixed in Tahoe trunk and 1.9.2 (soon to be released) by excluding PyCrypto 2.4.
