Did a clean install via TeX-Live 2022 onto a new mac. None of my old TeX files would compile. Reduced to the following and still won't compile.

Plain TeX using TeXShop, TeX+DVI.

---

```
\input pstricks

\input pst-plot

\noindent Hello, World!

\bye

```

---

Complains about an undefined control sequence \colorlet that seems to be used when pst-plot loads pstricks-add. It will compile if I don't input pst-plot.

Any ideas?
