No, you should not install your dependency package under dist-packages
before running bin/buildout.
Yes, it is fetched "magically". The magic is not grokproject's, but
comes from buildout:
http://pypi.python.org/pypi/zc.buildout
Which is what you executed when you ran bin/buildout.
Buildout's magic comes from setuptools (or distribute), and (by
default) fetches packages that are registered, in the Python Package
Index (PyPI, for short):
http://pypi.python.org/
MySQL-python is registered on PyPI at:
http://pypi.python.org/pypi/MySQL-python/
And you'll notice that version 1.2.3 is the latest registered there.
Cheers,
Leo
