Sounds OK to me.

This is weird though ... The "< 2.9.0" specification was there for quite
a while. I fear that the problem comes from rubygems, i.e. that the
rubygems server starts to need a more recent version. It did happen
before. This is worrying.

In the long run, I'll have to make sure that more recent hoe version
work as well.
