dang and blast!

I finally got Lazarus installed only to find I can't compile a new bare-bones GUI project

Code:
/usr/bin/ld: warning: link.res contains output sections; did you forget -T?
/usr/bin/ld: cannot find -lX11
/usr/bin/ld: cannot find -lgdk_pixbuf-2.0
/usr/bin/ld: cannot find -lgtk-x11-2.0
/usr/bin/ld: cannot find -lgdk-x11-2.0
/usr/bin/ld: cannot find -lgobject-2.0
/usr/bin/ld: cannot find -lglib-2.0

/usr/bin/ld: cannot find -lpango-1.0

/usr/bin/ld: cannot find -lcairo
project1.lpr(19,1) Error: Error while linking

This is the path to fpc source in the Environment/Options in the IDE:

Code:
/usr/share/fpcsrc/2.4.2/
