Just edit Makefile, and set the initial variables to fit your system.

Do not edit bellow the adviced point, unless you know what you are doing.

Then type "make" and, if everything goes fine, "make install" and follow
instructions on screen.

If you only want to compile and install one of the frontends (GTK or
ncurses), use "make gPpaSet" or "make nPpaSet" instead, and "make install-g"
and "make install-n" respectively.
