library) in `configure` aren't sufficient. (The [http://www-fourier.ujf-
grenoble.fr/~parisse/giac_compile.html instructions] to ''link to it'' on
Linux -- as opposed to ''building giac'', you listed giac's ''build
dependencies'' in the thread -- explicitly list also libao-dev.)

sufficient and there should be no reason why Pynac would need something
that isn't already there after `sage -i giac` has finished.
Yep, (vanilla) giac's configure instructions do not mention libao either.
But if building pynac ''may'' fail on !Debian/Ubuntu (hardly anyone uses
these distros, I know), pynac's configure should catch that case (either
by disabling giac, or giving an appropriate error message).
I'd say solve it upstream if you find the time, and we can eventually
revert the changes here with one of the next releases of pynac.
Or we could make Sage's giac package a standard one.

Can't parse that... 8-)
