I'm trying to get Google's Dart language up and running, but it errors when running dart2js. I'm running Arch linux and I installed dart-sdk from AUR. Some relevant terminal output lies below.

% dart2js main.dart   
/usr/local/bin/dart2js: line 7: /usr/local/bin/dart: No such file or directory

% cat /usr/local/bin/dart2js

% uname -rm

Could it be because I'm running a 64bit OS and the dart binary is 32bit?
