Can't run dart command line script using a symlink

What steps will reproduce the problem?
1.
I created a symlink in /usr/bin to /home/myuser/dart/scripts/bin/testscript.dart
2.
Unable to open file: /usr/bin/packages/args/args.dart'file:///usr/bin/testscript': error: line 4 pos 1: library handler failed
import 'package:args/args.dart' show ArgParser;
3.

What is the expected output? What do you see instead?
I think this should work to make Dart a convenient language for batch scripts.

What version of the product are you using? On what operating system?
Dart VM version: 1.2.0-dev.1.0 (Fri Jan 17 19:12:36 2014) on "linux_x64"

Please provide any additional information below.

A workaround I use now is to create a bash script named 'testscript' in the same directory as testscript.dart and link to this script instead

I lookup the current directory of the bash script and start the dart script
(http://stackoverflow.com/questions/59895/can-a-bash-script-tell-what-directory-its-stored-in).

#!/bin/bash
ME="$(basename "$(test -L "$0" && readlink "$0" || echo "$0")")"

SOURCE="${BASH_SOURCE[0]}"
while [ -h "$SOURCE" ]; do # resolve $SOURCE until the file is no longer a symlink
  DIR="$( cd -P "$( dirname "$SOURCE" )" && pwd )"
  SOURCE="$(readlink "$SOURCE")"
  [[ $SOURCE != /* ]] && SOURCE="$DIR/$SOURCE" # if $SOURCE was a relative symlink, we need to resolve it relative to the path where the symlink file was located
done
DIR="$( cd -P "$( dirname "$SOURCE" )" && pwd )"

${DIR}/${ME}.dart ${BASH_SOURCE[0]}

 
Instead of getting the command's (symlinks) name with io.Platform.script I have to pass it as an argument to have it available inside the dart script (I use the name of the symlink used to start the script like an argument inside the dart script)
This way I have to distinguish if the script was started directly and use io.Platform.script and args[0] otherwise.

I think this should all be easier.

I believe this is solved by issue #18538. Instead of symlinking, you would "globally install" the package (if you want a path package, see issue #19902), and then call "pub global run <package>:<script>" (see issue #19863) or create a shell script which does that, probably using issue #18539.

You are right, this is the global strategy ;-)
19902 is a real blocker.
I have no intention to publish packages for scripts I write to automate tasks on my local machine or my network.

I believe package maps are expected to address this.
