lablgtk can't find cairo (was: Re: Problem with cairo)

[Angela Zhu]

Sorry I didn't make it clear.
I want to use gSourceVIew library provided by lablgtk-2.10.0.
I first tried to use "port install lablgtk2", while it seems to succeed in
installation,
I cannot use gSourceVIew library because no "lablgtksourceview.cma" and "
gSourceView.cmi" can be find on my machine after installation.
But these two files are needed to compile OCaml program using gSourceVIew
library.

That's why I want to try install by hand after installing it using MacPorts
"successfully".

I did  "echo $PKG_CONFIG_PATH" but nothing found, how can I change this
parameter?

Again, I am confused, how could I set those parameters?
