Traversing /usr/lib/python2.6/vendor-packages, it looks like there
are almost no 64 bit packages installed. Is it possible to complete
the distribution so that at least numpy and its dependances are
available also in 64 bit ? For scientific stuff, arrays larger
than 2 GB are not so uncommon.


Do you have access to the C compiler which was used to build Python? 
If so, you can build any needed extensions yourself.  It is probably 
best to install them into a private tree managed by 'virtualenv' so 
problems are not caused by conflicts with package management.


An even better approach would be to build python 2.7 yourself into 
your own install tree so that you have complete control over it.

Of course I can build anything by myself, but numpy is already in
python-extras, but not complete, so to enable 64bit I would have
to reinstall the complete numpy by myself (which the colleague
who needs that has done already). I think if packages are offered
by the system, they should be complete, otherwise it makes no
sense to offer them at all since users then have to reinstall
by themselves anyway
