This is just a guess, but I would speculate that matplotlib installed its DLLs in 
C:\Python26\ArcGIS10.0\libs instead of (or in addition to) C:\Python26\ArcGIS10.0\DLLs.  If so, then 
you need to add the libs directory to your python path.  If it works in iPython, then fire up an 
iPython interpreter and print sys.path, and double check that all of the entries in sys.path are (a) 
in the PyDev PYTHONPATH and (b) in the right order.
