"I see some changes in in as.scm and ac.scm (esp the one that is being reported in the error message)."

If you're seeing those changes in the diff akkartik linked to, take a closer look. It's just whitespace. ^_^;

Pauan pointed out the "(require racket/unsafe/ops)" line in ac.scm. According to https://github.com/nex3/arc/blame/master/ac.scm, the line was added in this February 2011 commit (well before October!): https://github.com/nex3/arc/commit/cea8a4c5e9d1eb42f54b6c333...

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.

Thanks a lot for your reply :)

Looks like you originally had a version from somewhere between https://github.com/nex3/arc/commit/3201b34f3ed89e6305b0d9906... (October 14, 2010) and https://github.com/nex3/arc/commit/e05b3ef2aa9e4d298c7703a3b... (December 29, 2010). So "October" may be right! :-p

"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/ .

Now it works :) Thanks again !

Great. racket is the new PLT scheme. So it provides plt-scheme, but the opposite is not true.
