controlling the Arduino Nano with VEX Remote

hi guys,

we've been trying for some time to read signals off our VEX remote with the Arduino Nano but haven't had much luck.
we've used a library called ServoDecode from this post Decoding Radio Control signal pulses - Interfacing - Arduino Forum and it doesn't compile. it shows the following errors -

C:\Program Files\Arduino\libraries\ServoDecode\ServoDecode.cpp: In member function 'void ServoDecodeClass::begin()':
C:\Program Files\Arduino\libraries\ServoDecode\ServoDecode.cpp:76: error: 'INPUT' was not declared in this scope
C:\Program Files\Arduino\libraries\ServoDecode\ServoDecode.cpp:76: error: 'pinMode' was not declared in this scope

anybody got an idea what's going on here?

thanks
