Cheap UHF spectrum analyzer (and RC tx rx) using RFM22 module

I got my parts together now for a build of Zitrons latest board.

Works fine with the 'blink' test program.

When trying to compile the specan.pde - I get lots of errors due to missing files...
FastSerial.h
RF22.h
C++.h
Menu.h -- and many more.

@ Zitron,
I guess you use other library files when making your specan & Tx/Rx firmwares.

Is there some single download I can get the required lib files or do I need to hunt them down individually?

EDIT
Tracked down a bunch of missing lib files and now the only remaining compile error is:

C:\Arduino\arduino-0023\libraries\RF22\RF22_Specan.cpp:379: error: prototype for 'boolean RF22::setFrequency(float)' does not match any in class 'RF22'
C:\Arduino\arduino-0023\libraries\RF22/RF22.h:813: error: candidate is: boolean RF22::setFrequency(float, float)

What do I need to change/add??

/EDIT

So close and yet so far !!

Nigel.
