How would I integrate a usb to ftdi chip http://www.sparkfun.com/products/718  into this hackduino http://www.instructables.com/id/Perfboard-Hackduino-Arduino-compatible-circuit/#step1   ???

Have you looked at: http://www.arduino.cc/en/Main/Standalone

Assuming you have a bootloaded ATMega chip:
Connect These FTDI pins
Rx, Tx, Power, Gnd to the ATMega Rx, Tx, Regulator output, and Gnd pins.
(or leave off the regulator connection if the perfboard will be powered seperately while the FTDI is powered).
Add a 100nF cap to your board. Connect one side to ATmega pin1 (Reset) and the other to FTDI's DTR pin.

Why doesn't the arduino page have a schematic on it?

True, I am putting together a Hackino and find the lack for a schematic a bit of a worry, having to carefully look at where the wires go.

Have you a better source to building this?

The RBBB from modern devices is a very nice design and a good basis for a standalone.  There's a good schematic in the manual http://cdn.shopify.com/s/files/1/0038/9582/files/RBBB_Instructions_06.pdf

With the RBBB you use a separate USB to serial cable.  I bought one with my first rbbb and i've used it on a bunch of standalone and breadboard systems since.

FTDI board hooks up to the same pins as desribed earlier.
