[TurboGears] how do i import sqlbuilder ?

[Todd Greenwood]

How do I import sqlbuilder? The thread below shows:

http://groups.google.com/group/turbogears/browse_frm/thread/8995eb433f01b03d/6a3106bfb98c3933?q=sqlbuilder&rnum=1#6a3106bfb98c3933
#controllers.py
from sqlobject.sqlbuilder import LEFTJOINOn

That givos me: "ImportError: cannot import name sqlbuilder"

I'd like to do this:

class Entry(SQLObject):
        mod_date_time = DateTimeCol(default=sqlbuilder.func.now())

but I can't get that or any variant i can think of to work...so I'm
using:

class Entry(SQLObject):
      mod_date_time = DateTimeCol(default=datetime.datetime.now())

Any ideas?
