Loading meterpreter extensions in ms 3.0 beta

From what I can tell, the only way that this could happen would be if
the client-side script for stdapi failed to load.  I committed something
that should give a bit more verbose of an error message if this happens.
Can you verify that the following file exists:

Hello, thanks for helping me :)

I don't see those commands if I type help :(
(I also tried to grab the latest version from svn but there seems to be no change in behavior)

meterpreter > help

Core Commands

    Command       Description

    channel       Displays information about active channels
    close         Closes a channel
    exit          Terminate the meterpreter session
    help          Help menu

And if I try something like "use stdapi" i get the following error:

----- Original Message Follows -----
Meterpreter in version 3.0 is different from version 2.x.  Instead of
having a bunch of different extensions (fs, process, net, etc), the 3.0
meterpreter has this functionality merged into one extension called
stdapi.  When you exploit something with meterpreter, stdapi should
automatically be loaded.  If you type help, you should see all the
commands.  Is this not the behavior you're seeing?
