Hi,
besides the RHEL 5/Itanium we now also offer SLES 10/Itanium binaries
of Sage for each release. There will probably be little deman for this

dedicated access to such hardware it is and easy way to make sure

If you export SAGE_PBUILD=yes before you run make (so that it uses
pbuild from the beginning) it is necessary to link site-packages
yourself with the following command from $SAGE_ROOT:
ln -s devel/sage/build/sage/ local/lib/python/site-packages/sage
This will be fixed in rc0.

Thanks for posting the example. It will be more interesting to look at

Yes, but we are getting better at it. For example look at Didier

I think Sage is awesome. I've started using it in my research. I've
been using it to teach classes, and I've even forced my students to

Yes, Sage has lots of bugs, but at least I get to see the code, and if
I'm motivated then I can even fix it myself.
