Here. (s/I’m/I/)
> I want to give fabric a try (as recommended here: http://www.jeffknupp.com/blog/2012/10/24/starting-a-django-14-project-the-right-way/). Installing fabric results in two dependencies (paramiko and pycrypto) being installed as well. All is dandy until it is time to install pycrypto.

Note that Fabric is useful for much, MUCH more than this.

Off-topic: why is your virtualenv/project name so weird?

Seems to be properly installed.

Here comes your problem: you do not have the Python header files,
required to compile the C code used by pycrypto (for speed in certain
operations, because they are quite resource-intensive).  Where can you
get them?  I don’t know, ask your distro.  They are usually in a
package ending with -dev or -devel (depending on your distro; human
distros do not bother with this and ship them along with the rest of
the thing…)
