same issue as me (though i am working on a different app) but getting the environment setup is so confusing because there are so many options and too much information.

the easiest way is to use the VM virtual machine

download the one called Maemo_Ubuntu_Lucid_Desktop_SDK_Virtual_Image_Final .7z

then go to vmware and download vmware player 2.5 and your environment will be ready in less time than you can say supercalifragilisticexpialidocious
