Maybe you are selecting the wrong board type when you are uploading the program with the FTDI cable?

I have several Atmega 328s on stripboard and I have never had the problem you describe. IIRC  I choose the Lilypad board when I upload to my 8MHz Atmega 328.

Two or three hours spent thinking and reading documentation solves most programming problems.
