On el capitan, arduino IDE does not "see" any usb ports, only /dev/cu not /dev/tty
tried with 1.6.8 and the latest hourly build

cannot program any boards :(

/dev/cu and /dev/tty are the same, as far as Arduino is concerned.

Technically, /dev/cu.usbmodem is the proper type to use. /dev/tty.usbmodem is meant to be used for modems with a RI (ring indicator) and DCD (carrier detect) handshake lines. But the libraries Arduino uses are able to deal with either type.

Indeed, cu and tty are the "same" thing, the problem seems to be El Capitan. Closing as duplicate of #3928 (the issue is closed but we are keeping all the conversation/workarounds there )
