Thank you for that!  I'm not sure how I missed it the first time.  But
alas, this gives me more output about the download and unpack (which
work fine, AFAICT), but the Chicken invocation itself does not give me
any more output than before.

I specifically checked this beforehand.  I can compile C programs that
use OpenGL just fine:

ii  libgl1-mesa-dev                      7.0.2-4
ii  libglu1-mesa-dev                     7.0.2-4
ii  mesa-common-dev                      7.0.2-4

I should also mention that I'm using Debian sid, since I don't
remember mentioning it before.  There's a chance there's a bug
somewhere down the toolchain that's only showing up here, but I still
have some trouble getting enough information to diagnose it.

Still no go.

Upon slightly closer inspection, it appears that Chicken is actually
silently segfaulting, at least if the kernel logs are any indication.
Hum.  Now that I am being less ignorant about the debugging options, I
tried [chicken-setup -v -csc-option -verbose opengl], which resulted
in this:

Unfortunately, I know little enough about Chicken's internals that
this doesn't help much, but perhaps it will yield better results for
someone else...
