On Debian (and derivatives) you need to install libwxgtk2.8-dev (for the 
wxt terminal), libpango1.0-dev (for the cairo terminals) and 
libreadline5-dev (readline support (editing command lines). Follow the 
configure/make steps below and you should have wxt and the two cairo 
terminals. Carefully inspect the final lines of the build output since 
this tells you what has and has not been included; if anything you need 
is missing you will need to hunt down the necessary dependency.
