BackgroundRB persistant job table not created


I have used backgroundrb plugin in my application,

I followed the tutorial in,

Everything works fine,
When I run rake backgroundrb:setup,
It created the required scripts, and backgroundrb.yml but the mirgation
files were missing.

Can some one help me out y this happened or with providing the default
miration file which it generates,


I use rails 2.2.2
Backgroundrb version (latest from svn)
