If connecting to serial port works when you run pd with sudo privileges, you will need to add your user is to the dialout group. See http://unix.stackexchange.com/questions/14354/read-write-to-a-serial-port-wi... for more info. HTH

I have done all of that for use with the ardunio uno, it's when the raspi2 is directly connected to the serial pins that it does not connect. I tested the device on mac and used the ALLINPUTS firmata and it works with a virtual serial created by FTDI just can't seem to talk to it with Linux debian running vanilla
comport works fine with the UNO

mknod? this sounds like you are following advice from the 1990s. these days mknod is hardly ever needed: instead any devicefiles will be created on the fly by the resp. drivers.
selecting device in the toggles in the pduino stuff only finds device 0
I am wondering if it's a linux issue because the only serial port at all is
serial 0 /dev/ttyAMA0
a little bit of googling hints that /dev/ttyAMA0 is indeed the name for the serial interface on the GPIO ports - which afaiu is what you want.
so you just use that device.
then you need to get the permissions correct. check whether the device is already setup to allow group-members to write to it, and which group that is: $ ls -l /dev/ttyAMA0 crw-rw---- 1 root dialout 4, 67 Sep 3 16:12 /dev/ttyAMA0
and eventually add the user running Pd to that group: pd@raspbian $ sudo bash root@raspbian # adduser pd dialout
after that you only need to re-login as that user to let the new group membership have any effect.
