I would do it like this:

1 - Install Free Pascal normally from the distributions packages

2 - Download the lazarus source to a directory in your user dir. Instructions here:

http://wiki.lazarus.freepascal.org/index.php/Getting_Lazarus

3 - Go to the directory where you put the lazarus source, on the command line and type:

make clean all

if you want a Gtk 2 IDE you can do:

make clean all LCL_PLATFORM=gtk2

You need to have installed all pre-requisite packages for lazarus, which are either gtk1 or gtk2 and gdk_pixbuf development version.

Now you can create a link to the startlazarus executable on the desktop and that's it.
