This is what worked for me to install it on Squeeze 64-bit:

$ sudo aptitude install libqt4-dev g++ libgpgme11-dev libgpg-error-dev libupnp-dev libssl-dev libgnome-keyring-dev libxss-dev gnupg-agent

If this asks you to remove packages, DO NOT CONTINUE.  The above line should only INSTALL packages.  Fix your system first.

$ wget http://sourceforge.net/projects/retroshare/files/RetroShare/0.5.3c/RetroShare-v0.5.3c.tar.gz/download
$ tar xzvf RetroShare-v0.5.3c.tar.gz 
$ cd trunk/libbitdht/src
$ qmake && make
