Missing Cython makes import pytables fail on importing utilsExtension module

[rawphi]

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:

ImportError: No module named utilsExtension

[David Fokkema (dfokkema)]

No longer affects natty.

[Julian Taylor (jtaylor)]

you seem to accidentally import a file from your home folder which causes the problem.
/home/raphael/Desktop/simulation/hdf5Extension.pyx in hdf5Extension()

the import statement succeeds for me in lucid.
