It seems it must have been a problem with my install of sage from the
sage-on-gentoo overlay (I am the main committer there and try to have
the thing working on prefix too). Now that I have completed a full
upgrade it emerges like a charm.
Just for the record on why sage is relevant here: sage uses sympy
(runtime) if sage is present sympy uses bits of it (runtime detection),
so things are a bit circular. But there is more! sympy imports itself at
install time....
