Reduce algebra system successfully built on DragonFlyBSD 5.2

[karu.pruun]

Hello

Cool you could build it! However, reduce is available as a port and a
binary package on DragonFly 5.0, 5.2 and master.

% pkg search reduce
reduce-20180117                REDUCE Codemist Standard Lisp
general-purpose computer system
% sudo pkg install reduce-20180117

installs the snapshot as of Jan 2018. DragonFly follows FreeBSD's
ports when possible and reduce does not seem to need anything
DragonFly specific at the moment. Regarding how to create a port, have
a look at math/reduce in /usr/dports on DragonFly.

Cheers

Peeter
