I made some little changes to travis.yml, anyway I still get an error in WireClass, looks like endTransmission doesn't accept any parameter (https://travis-ci.org/nanpy/nanpy-firmware)

build/local/WireClass.cpp: In member function 'virtual void nanpy::WireClass::elaborate(nanpy::MethodDescriptor*)':

Passing! I updated Arduino to 1.0.5 in travis config. The Wire interface changed in 1.0.1 and TravisCi has only 1.0.
