Agree though that some pre-built binaries would be fantastic!
It's considered really sloppy and unmaintainable to admin a system like that. Things quickly get out of hand.
That strategy _does_ work if you isolate it to a chroot or a container, but littering /usr/local with all sorts of locally compiled upstream is just asking for future pain. Security updates, library incompatibilities, &c.
Prebuilt binaries might be nice, but I don't expect them for random projects. (and I wouldn't have used them if offered) I do think it's a reasonable expectation to be able to build software w/o essentially setting up a new userland just for that tool though. :)
I'm sorry, and retract my ignorant assumption! Going to try it out now.
I've also had requests from Alpine Linux packagers to allow dynamic linking to parsers. This is something I want to support in future, once I'm happy with the basic diffing logic.
