ok now we are getting somewhere. looks like a hiccup installing the dependencies so lets just try to install them all again to make sure nothing is missing
in terminal:
sudo apt-get update && sudo apt-get install -y libboost1.50-dev libboost-filesystem1.50-dev libboost-system1.50-dev libboost-program-options1.50-dev libboost-thread1.50-dev libssl-dev libdb5.1++-dev libminiupnpc-dev
this will ask for your root password and to confirm the installation of whatever is missing and you can just say yes
ok, entered that but it didn't ask for a password. said some things failed to download. should I run that first bit of code again?
