[TxMt] GetBundles installation problem

[Piero D'Ancona]

I just installed  GetBundles and it does not work for me.
If I invoke the GetBundles command, a tooltip appears
saying 'unknown command, try help'

Narrowing down the problem, the script breaks down
immediately at the first invocation of "$DIALOG".
Needless to say I have the cutting edge TextMate and
tm_dialog2 is at its place, which coincides with the path
given by echo "$DIALOG"

Any ideas?

Thanks
Piero
