It essentially boils down to:

[cc]checking whether we are cross compiling… configure: error: in `/tmp/pip-build-root/pycrypto’:
configure: error: cannot run C compiled programs.
If you meant to cross compile, use `–host’.
See `config.log’ for more details[/cc]

Weird, I have gcc and all compile programs installed.

It took me a fair time of troubleshooting, but I finally figured out it was because it was attempting to build this in /tmp, which I have set to mount at noexec for security purposes. This disallows execution of programs in this directory.

Running

[cc]mount -oremount,exec /tmp[/cc]

Allowed it to run without issue.

Install CAB files directly to a Windows Mobile Device from your Desktop via ActiveSync

Downloading a CAB file to install onto your Windows Mobile device can be a pain – after downloading the cab file to your desktop, you need to first copy it to your device, then find the cab file to install and then proceed to install it.

CABviaActiveSync is a simple, free program that adds a context menu to automatically parse the cab file on your desktop and install it via activesync. This can save you a bunch of steps and is incredibly handy if you are like me and are always installing/uninstalling programs to check out.

Download CABviaActiveSync from Modaco.
