That's great; are all these libraries available on OS X by default? If
the answer is yes, then, together with John's Windows builds, we would
at least have complete builds for the two major platforms.

Here is a very short piece of code. This should fail if one of the
libraries is not there. The garbage collector cannot be tested in this
way, unfortunately. If a shared library is expected but missing, the
loader simply refuses to execute the program.

size(4cm, 0);

// Test GSL
access gsl;
write(gsl.sinc(0));
write();

// Test FFTW
int n = 4;
pair[] f = sequence(n);
write(f);
pair[] g = fft(f, -1);
write();
write(g);
f=fft(g, 1);
write();
write(f/n);
write();

// Test OpenGL
access settings;
access three;
settings.render = -1;
settings.outformat = "png";
three.draw(three.unitsphere);
