I could not get the arduino pro mini to work with just comport no matter how i tried, so i installed "Pduino" and after installing
pd-mapping, pd-pure, pd-moocow [pdstring] i got it to work

Funny I was just working on this this morning looking for a simple solution for my students.
I found this http://colinzyskowski.com/?page_id=503 to access analogRead.
It kind of works. The third pot interferes with the other two and when I modified to code to add a fourth it interfers or doesn't work at all. Seems to be something to do with the map function Arduino code not workign correctly because when I poll [comport] with [print] each analogRead seems to be on it's own "channel". I can't figure out how to separate them any better than using [split] with there mapped values (not great). I tried [unpack] and [route] but neither of these separate the data streams.
On the hardware side I just have each 10k pot wiper connected it's own analog pin on the Uno and each pot is powered and grounded from the Uno via the rails on my breadboard. I'm guessing but adding in some resistors might stabilise the circuit a bit, I don't know if this would help with the interference or not.
As mentioned above I also had to add a dialout to access the serial port as outlined by Rinzwind here http://askubuntu.com/questions/58119/changing-permissions-on-serial-port

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

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.
