Then read my dear fellow ;)

OK, so it sets the directories for libraries to the ones specifies with -L
and the libraries to the libraries specified with -l to link with. Btw,
this will yield errors on in my compile attempts since I have to -lgmodule
as well.

Then it's awkward that it responded with the `directory doesn't exist'
error.

If yer system is ELF and the linkage is specified to shared, then it will
use the .so libraries.

libm is the mathematical library, which includes functions like sin, cos,
etc. This _is_ needed for GTk+ for drawing.

Yer learning =)

Correct, as a sort of easy reference script for compilation flags. Who is
to say that my GTk+ libraries reside in /usr/local/lib?
