[Distutils] Where is distribute at pypi?

[Daniel Holth]

There's your problem.
https://code.google.com/p/pydicom/source/browse/source/setup.py . It's
trying to install distribute as a side effect of running setup.py, so
it can import setuptools. This is now discouraged. The best solution
would be to remove the first 3 lines of that file. Setuptools is
guaranteed to be available when installing with pip.
