How to specify install order for python pip?

Question

I'm working with fabric(0.9.4)+pip(0.8.2) and I need to install some python modules for multiple servers. All servers have old version of setuptools (0.6c8) which needs to be upgraded for pymongo module. Pymongo requires setuptools>=0.6c9.

My problem is that pip starts installation with pymongo instead of setuptools which causes pip to stop. Shuffling module order in requirements file doesn't seem to help.

requirements.txt:

setuptools>=0.6c9
pymongo==1.9
simplejson==2.1.3

Is there a way to specify install order for pip as it doesn't seem to do it properly by itself?

This can be resolved with two separate requirements files but it would be nice if I didn't need to maintain multiple requirements files now or in the future.

Problem persists with pip 0.8.3.

You can just use:

cat requirements.txt | xargs pip install
