Well, I don't know about you, but it wasn't obvious to me that running
easy_install against an .EXE would (a) work at all or (b) work in a
virtualenv. And, yes, I do know about the Voidspace page; the same
link is right there in the middle of my message. Thanks to Michael
Foord for making the installers available to everyone.
This thread will have some google juice for future searchers.

With all the export regulations, I can understand why you might not want to supply pre-built binaries, but it would be good to explain how to do it. Michael Foord has supplied such binaries for earlier versions of PyCrypto, but there's none available for PyCrypto 2.5 yet.
