Let's tackle them one by one. First, install the packages that can be installed:

sudo apt-get update
sudo apt-get install build-essential git-core flex bison gperf lib{esd0,wxgtk2.8}-dev squashfs-tools

Then try:

sudo apt-get install libcurl3 curl

sudo apt-get install lib{pulse,glu1-mesa,sdl1.2}-dev
