There are two issues that I saw.  First, the matplotlib egg above does not 
declare a namespace in its matplotlib/__init__.py.  Second, the basemap egg 
does not contain a matplotlib/__init__.py at all.

Please note that you *must* include an __init__.py file for every namespace 
package and parent package thereof, in *every* egg that's part of the 
namespace package, and that these __init__.py files must all contain a 
namespace declaration.  Missing even one can cause problems.  For example, 
the basemap egg is simply not importable, because as far as Python is 
concerned it does not contain a matplotlib package (due to the missing 
__init__.py).
