I see some changes in in as.scm and ac.scm (esp the one that is being reported in the error message).
The debian package description of racket (http://packages.debian.org/sid/racket) says that the package was previously plt-scheme. So, I seem to be using it :(
The main point is that you want something that works, right? :) If updating Racket isn't working for you, maybe for now you can revert to an older version of Anarki. The commit before the racket/unsafe/ops one is https://github.com/nex3/arc/commit/b36f223bfba2e12e518fff955..., which you can get to like this:
$ git checkout b36f223b
If you want to get back to the Anarki tip, do this:
$ git checkout master
Be careful if you have changes in your working copy.
I must have done some mistake then. I admit that I didnt see akkartik's link before posting that reply. I think my downloaded files are older than October- the directory has a timestamp from October and the ac.scm file has a timestamp from August 2009. The diff is here: http://pastebin.com/BLp6p69v
Yes, I would like to use something that works, and something that is as latest as possible :) I seem to be using Racket (in the form of plt-scheme) and it seems to work for an older version of arc. The point of my question was if I needed to do something to keep up with the changes made in Arc.
"The point of my question was if I needed to do something to keep up with the changes made in Arc."
Then making sure Racket is up-to-date is the answer you're looking for, as you already know. :-p Have you been successful running the latest Anarki on your Racket install yet? What do "racket --version" and "mzscheme --version" say now?
Hi,
Thanks a lot to your earlier comment, about running "racket -f as.scm"- I found out that racket couldnt be located by the system. Something must be unclear with the description of Ubuntu/Debian packages- I got an impression that "plt-scheme" contained racket. I manually installed racket by downloading from here: http://racket-lang.org/download/ .
