Grails doesn't add /usr/share/grails/downloads directory with correct permissions

[GoogleCodeExporter]

What steps will reproduce the problem?
1. install the grails package
2. create a grails project + install a plugin
3. You will see that the 'downloads' directory is not writable

What is the expected output? What do you see instead?
It should have been created by the installer and made writable, or moved to 
the user's home directory and made writable

What version of the product are you using? On what operating system?
Ubuntu 9.10
Current release
Grails example

Update to this - the /usr/share/grails downloads directory should not be 
created.

What should happen is that the downloaded plugin cache should be pointed to the 
user's home directory under ~/.grails/...

I am trying to determine where a vanilla grails installation puts this 
directory so that I can modify the build process to mirror that behaviour.
