It will probably confirm eventually, but it could take several days.
I haven't had much luck running pywallet on a Mac. You could manually build a new wallet that doesn't include the transaction by using importprivkey, but it would be a lot of work, and probably not worth the effort.
If it hasn't confirmed after a few days, you could import just the private keys associated with that particular transaction and create a raw transaction spending the same inputs but paying a transaction fee.
Ok, but how to import or export priv key for a specific transaction on Bitcoin-QT?
Do i have to create a new wallet in the end or use the same wallet to send raw transaction? And also i don't have the balance to send again so i guess, or i have to wait until confirmed or delete transaction and wait until the funds return back.
