I am wondering what Sage's strategy is with regard to coercions.
It thought that it would be reasonable that an element of a
RealIntervalField
should be coercable into a RealField but this does not seem to be the
case.
sage: r=RealIntervalField(16)((1,2))
sage: RealField(16)(r)

In sage-2.0 and sage-2.1.0.1 the first Axiom command that I enter
hangs the sage process but if I hit control-c and re-enter the
command, it works as it used to work. This also affects Axiom
commands entered via the notebook.
sage: axiom('1+1')
... waits indefinitely ...

Thanks, that worked. During the initial 'sage -upgrade' step,

My troubles with Fedora Core 5 disappeared after a fresh start.
sage-2.1 builds now and starts normal. make -test has only
one test failing: intgration.pyx on floating point issues.
My upgrade system wide from 2.0 to

A fresh install on FC 6 succeeded with only one test failing:
