Guile OpenGL

[Tim Meehan]

I tried to configure Guile OpenGL with Guile 3.0.4 ... and I had to make
the following change in order to make it work (included below).
Apparently, it wants to be installed in:
/usr/local/lib/guile/3.0/ccache

Apparently I need to change some configuration.
Adding this to "~/.guile" didn't work:
(add-to-load-path "/usr/local/lib/guile/3.0/ccache")

This worked (all on the command line before calling the guile executable):
GUILE_LOAD_COMPILED_PATH=/usr/local/lib/guile/3.0/ccache guile
(I'm probably just going to add that environment variable to ~/.bashrc)

Is there a "more correct" way of making guile aware of this?

(Small tweak to "configure" below:)
