  Sage uses ecl-11.1.2, that defaults to --enable-unicode=no, and fedora
has ecl-12.2.1 (actually, fedora 16 has ecl-11.1.1 that should just work,
but I am building rawhide packages, as goal is to have sagemath for
fedora 18...)... So, attempting a test ecl build with --enable-unicode=no
fails in make check, like this:

Condition of type: SIMPLE-ERROR
Unknown or unsupported external format: UTF-8
No restarts available.

  I will try to debug the conditions that lead to either to see if I can
make it agree on features of the string object.

> gap and singular appear to have worked at least for a very basic test.

pari-gp also works, I just had not installed back the pari-gp package I built.
