Hi Nicolas,
I'm assuming the subject line got your attention. :) I've been working
on a basic implementation of quasisymmetric functions (monomial and
fundamental basis only, no Hopf operations) and I already have something
that seems to work. Without using sage-combinat. Hooray! Three cheers
I suggest that you contact the pari developers about this. they may
not have access to a Solaris machine, in which case it would be harder
for them to help, but it is worth a try. email Karim Belabas and/or
Bill Alombert.

It would be possible to adapt the theta code we used for the trillion
