Not in pkgsrc. It's just downloaded from Lars' site:

I've helped him find an overflow problem with the random generator, which
was causing my NetBSD 1.5 DEC 3000/400 to generate 0 or 1 for every single
number it made. (ratio of 0's created to 1's created was about 45:1 *grin*)

P.S. If you're compiling this on a pmax, with NetBSD 1.4.x, you may need to
use the unlimit command. I got "out of virtual memory" error messages when
trying to compile interpret.c with any sort of optimisation on my 1.4.2
pmax.
