From Tom Parker:
They are available by adding the following lines to your /etc/apt/sources.list
deb http://tevp.net/debian/ binary/ deb-src http://tevp.net/debian/ source/
and then running "apt-get update", followed by "apt-get install omnetpp-static". As the name suggests, the package only currently has static library versions of OMNeT++ not the shared versions, but I will be expanding this to include shared versions at a later date.
