on the first step, I am getting this :
The following packages have unmet dependencies:
 libminiupnpc-dev : Depends: libminiupnpc8 (= 1.6-3ubuntu1) but 1.6-precise2 is to be installed

I guess i already have libminiupnpc8 installed but just the wrong version? someone know what i need to do to correct it ?

thanks in advance
