I'd try Arch, I heard it has decent support for rPi and it's a pretty stable distro. Also I think the proper command is "./cgminer -o stratum.bitcoin.cz:3333 -u xxxxxx - p xxxxxx" while in the cgminer folder.
I tried that from the cgminer directory and got the same error. The exact error is "Pool 0 JSON auth failed: (null)"
As a work around I guess I might try setting up miner.conf with all of my pool information in there. Maybe that would take care of things.
I should probably add that just using cgminer says I don't have permission to access the devices. I've been starting it with sudo cgminer. Should I continue to do it this way or change some kind of user permissions?
Thanks!

Try bfgminer,
1: Open Terminal or SSH into your Linux machine.
2: Run "apt-get update"
3: Run "apt-get install git autoconf automake libtool pkg-config libcurl4-gnutls-dev libjansson-dev uthash-dev libncurses5-dev"
4: Run "git clone git://github.com/luke-jr/bfgminer.git"
5: Enter the bfgminer directory
6: Run "./autogen.sh"
7: Run "./configure" (if you do not want to use GPUs on the machine, add --disable-opencl)
8: Run "make"
9: After make completes, you can run bfgminer directly (may require sudo), or create a shell script that includes your arguments.
Running BFGMiner:
./bfgminer -o stratum+tcp://pool:port -u yourUSERNAME -p your_PW -S all --icarus-options 115200:1:1 --icarus-timing 3.0=100
good luck
