wxMaxima, mentioned above, works fine for me although it is marked broken,
both in current and in 6.2 stable.
I first reported to ports on 18 June 2017 that wxMaxima, works fine for me
in 6.0, if I remove the "broken" line in the Makefile.
More recently, upgrading 6.0 -> 6.1 -> 6.2, I found I had to delete that
package, once again remove the "broken" line, then re-make/install.
So it is still the case for me, using ports from 6.2 stable, on a
release version of 6.2, wxMaxima works great.
Studying solar power for our farm, taking an Edx.org course at xDelf, the
following script earns me a correct couple of points in the problem sets
at the end of week two...
Using 4 wxMaxima "cells", script, including comments, are entirely
mine...
