Need help installing SIMBL ITT

I am installing it from the following site :http://www.culater.net/software/SIMBL/SIMBL.php.

Once i installation is complete, I cannot access it under library/application support. there's no folder.

I have tried installing it several times and it still hasn't worked. I am currently using Mac OXS 10.5.8 (and safari 4)

Any ideas?

 

Update. I figured it out. all i had to do is create the folders myself.

Now i am faced with another problem: The greasekit does not work with safari 4. all scripts that i have installed did not work. what can i do?
