Install package on already unsupported ubuntu

[nignasi]

Hi all,

our students laboratory is equipped with ubuntu Intrepid Ibex.
Now we need to install gnuplot and synaptic manager fails because Intrepid is unsupported. I know we can update to a newer version but we cannot do it now (we'll do it during summer holidays).

What's the best way of installing gnuplot (or some other aplication) on our systems? Should we download from sources and compile? Could we add some special source to our list and download from there?

Thank you,

Ignasi
