I have found that the easiest way to identify necessary development libraries
on Debian/Ubuntu is to download the source package for a version of octave
already available in the repositories.  For example, "apt-get source octave2.1"
will download the source package for octave2.1 in your current directory. 
Check the file with the ".dsc" extension, as this gives all the prerequisites
to build the package.

Another approach is "sudo apt-get build-depends octave2.1".  This automates the
installation of the build dependencies for the octave2.1 package.  Most likely
this will pick up the build dependencies (or at least most of them) for your
octave 2.9.4 build as well.
