run.sh does not work from /usr/local/bin or equivalent

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Install codeswarm into /usr/local/share or equivalent
2. Install or symlink run.sh from /usr/local/bin or equivalent
3. Run codeswarm

What is the expected output? What do you see instead?

Codeswarm should run, fails to find jar 

"ERROR, please verify 'ant' and 'java-sdk' installation" 

What version of the product are you using? On what operating system?

Latest trunk 

Patch attached to resolve this. Used the code from the ant project's launcher 
script 
(ANT_HOME/bin/ant). Not sure if that causes a license problem? Also only tested 
on OS X.

Cheers,

Matt

On Ubuntu 10.04, I changed JAVA_HOME to
export JAVA_HOME=/usr/lib/jvm/java-6-sun/
to make it work
