[Bug 509100] [NEW] Missing Cython makes import pytables fail on importing utilsExtension module

[rawphi]

Public bug reported:

Pytables package is missing the dependency on the Cython package, and
thus (if cython happens to not be installed otherwise) will fail to
load. this bug is in both 2.0.3-1ubuntu1 (karmic) and 2.1.2-3 (lucid)
packages

fix: install cython package manually (apt-get install cython)

Error message when loading tabels:

In [60]: import tables
---------------------------------------------------------------------------
