What version of Ubuntu? 12.10 should have Octave 3.6. If using Ubuntu
12.10 you're getting Octave 3.2 instead, there's a packaging bug.

Depending on the package, it is in fact more difficult. For example,
for the symbolic package, you'll have to chase down the GiNaC
dependencies yourself. You'll also have to manually fix the packages
yourself and chase dependencies again when you upgrade the Octave
version instead of letting apt do the chasing. With pkg.m, you're
essentially compiling and installing packages yourself instead of
getting the benefits of a robust package manager. Thus, apt is a far
better long-term choice than pkg.m.
