Hi John,
You can either use ASDF (CL 'make'-like facility) or now quicklisp.
If you're on LW 6.1 you can type (require :asdf) which will load the version of ASDF that's bundled with LispWorks. Then load cl-opengl.asd file, and type (asdf:oos 'asdf:load-op :cl-opengl).
If you don't have ASDF get it here:
http://common-lisp.net/project/asdf/cl-opengl depends on CFFI, which itself has dependencies, and it's much less of a headache (especially on Windows) to use quicklisp to acquire and load libraries. For instructions go here:
http://www.quicklisp.org/beta/Another alternative is the LispWorks defsystem facility, so long as the library has a valid LW defsystem file.
When you define a package you can use (:use <package name>) to reference symbols available in the package without qualification.
Best,
Christopher
