I think you should do yourself a favour and scrap the Ubuntu Erlang 
package and instead go for installing yourself the source version of 
R13B03, which builds .beam files with debug_info in them (as it should).

Besides the ability to run dialyzer on your code, you will end up with a 
better/newer Erlang system.  The installation process itself should be 
trivial.
