I've played around with NTL a bit, and once you've got the hang of using
those numerous conversions, I find it quite easy to work with. When it comes
to factoring polynomials over Z[x] or Zp[x], NTL is the best tool you can
get. So you could do a lot worse than integrate NTL in GiNaC. I don't know,
though, how this integration should be done technically since NTL uses its
own number classes that may confict with CLN's.
Also, NTL doesn't support multivariate polynomials, calculations in Q, and
algebraic extensions of Q.
As for the ginsh installation, yes, you were right. The rpms worked fine.
Don't know why I didn't use them in the first place.
