can't install jamvm

[Paolo Compagnini]

hi there,

i'm running ubuntu 8.10 64bit.

when firefox tries to laod a java applet it will freeze. (you have to
kill the process)
that's because jamvm is not installed. but libffi4 (>= 4.2.1) which is
needed to install jamvm seems not to be in the repos.

console output:
Die folgenden Pakete haben nicht erfüllte Abhängigkeiten:
  jamvm: Hängt ab: libffi4 (>= 4.2.1) ist aber nicht installierbar


( it's german sorry :-P )
