Naw. Didn't work for me.
I have Gutsy, pidgin-dev, I installed build-essential as well.
neither ./configure, nor make or make install are giving any Errors. I checked the Plugin in Pidgin and added %rb to Away-Message. I even restarted Pidgin and Rythmbox. I switched through some Songs, but nothing.
Nice Guide. But didn't do it for me. :/
i experienced something like this when i did the install not realizing either rb or pidgin was minimized but running. id give it another go making sure both are off completely.
