Building herkforth
If you have a PPC GNU/Linux box, you can follow these instructions to build herkforth. If you run Linux on a different architecture (eg x86) you can download herkforth-bin (from the herkforth page) and run it with qemu.
Sorry, there's no installer. This process creates a binary that you can move wherever you like.
herkforth has no installer, but you can move the binary anywhere you like as it's completely self-contained.
just:
$ make
This creates a binary called "herkforth000" in the current directory.
When you run it it will automatically generate herkforth001
