Here is the current portfile with variants galore. I don't know if it's a good candidate for using subports, or not. RS had suggested it because of licensing differences between csl and psl.

description             REDUCE Computer Algebra System

long_description        REDUCE is a system for doing scalar, vector and matrix algebra \
                        by computer, which also supports arbitrary precision numerical \
                        approximation and interfaces to gnuplot to provide graphics. \
                        It can be used interactively for simple calculations but also \
                        provides a full programming language, with a syntax similar to \
                        other modern programming languages.
