Agreed. First, check that your files are really compiled (you should see a newEngine.so in install dirs). If they are not, it is probably due to a missing declaration in SConscript files (those files define what needs to be compiled and the dependencies between classes). Just copy/paste/rename the GravityEngine section in dem/Sconscript (or common/SConscript, not sure).
IIRC, the preprocessor will not appear in the interface if one of the plugin (the library corresponding to your new class) is not found. I think this will happen as soon as you declare the missing class in your code, it doesn't matter if you use it or not. Don't you get any compilation errors? warnings when you start Yade? If I understand correctly, you will need to play with distant interactions (without contact), which means you could be interested by the current discussion on this topic here : http://yade.wikia.com/wiki/Sanitizing_Contact_Logic.
