$BIN/dart2js, $BIN/pub in SDK do not support symbolic link

$BIN/dart2js, $BIN/pub in SDK are shell scripts in fact. But the dirname $0 does not support symbolic link way.

how about:
BIN_DIR=dirname $0
->
BIN_DIR=dirname $(readlink -f $0)

it works in my arch:)

I don't believe we have fixed this problem yet.

If you have a link from /a/b/c/d/e/f to /opt/dart-sdk/bin/dart2js, dirname of a/b/c/d/e/f will return /a/b/c/d/e. That's not where the Dart SDK is.

I think this will work:

PROG_NAME="${BASH_SOURCE[0]}"
while [ -h "${PROG_NAME}" ]; do
  PROG_NAME="$(readlink "${PROG_NAME}")"
done
BIN_DIR="$(cd "${PROG_NAME%/*}" ; pwd -P)"
