imaxima in Aquamacs Emacs 22.3.2

[viona]

Dear all,
I've  been struggling to make imaxima work properly on Aquamacs.
But when I start imaxima, it gives me each time "Latex error in:"
message.
(e.g.
(%i1) factor(10!);
LaTex error in: 2^{8}\*3^{4}\*5^{2}\*7)

I googled, checked my breqn package and made texhash, I have
ghostscript installed,
 but still from here I don't see how the issue could be solved.

Any help would be highly appreciated!
