Just a heads up on the compiling guide at
http://planeshift.svn.sourceforge.net/viewvc/planeshift/trunk/docs/compiling.html It looks like
libglu1-xorg-dev no longer exists in Ubuntu and installing
libjpeg62-dev will trigger the removal of
libjepeg-dev, libjepeg-turbo8-dev, libjpeg8-dev, and libmng-dev. However, you can simply skip the installation of
libjpeg62-dev and everything will compile just fine.
