I haven't tried OSX myself, but with recent versions of MzScheme you should no longer use the "-m" option. Try just "mzscheme -f as.scm" and see if that helps.

Also, if you try just "mzscheme" without any arguments, do you get an mzscheme prompt like this?

if you still get the "Abort Trap", there's a problem with your MzScheme installation. You could try downloading directly from http://racket-lang.org/download/ (mzscheme got renamed to Racket). If you can't get MzScheme / Racket to work, you can also ask for help over on http://racket-lang.org/community.html

hey aw, this is saying that arc still requires MzScheme? https://github.com/mxcl/homebrew/commit/547edb0d39175a2e3898...

It's wrong. "racket -i -f as.scm" works fine and I've been using it for a few months. (Note that this is for arc3.1, which you are using, so that should be fine.)

Though I switched temporarily back to PLTv4 after reporting this bug: http://bugs.racket-lang.org/query/?cmd=view&pr=11380 (since fixed at HEAD)

That fix is also in 5.0.2.

thanks waterhouse. Did you install from src? I'm a little unsure about the configure option. I'm assuming "--prefix=/usr/local/racket --enable-macprefix" ?

I didn't install from source, and have no idea about doing that. What I do to install is: Download DrRacket from racket-lang.org. Move it to the Applications folder as is conventional. Add to the ~/.bash_profile the following line:

  export PATH=/Applications/Racket\ v5.0.2/bin:$PATH
Now you'll be able to use the "racket" and "mzscheme" and "raco" and all other programs from the "bin" subdirectory by just typing their names. (This applies to any terminal windows opened after you've changed .bash_profile.)
