Error compiling code

[Cameron]

Hi all-

I'm running Arduino 022 with Teensyduino installed. Board selected as
Teensy 2, USB Type selected as Serial. I get the following error when
compiling:

Octomod/spi.c.o: In function `setup_spi':
/Applications/Arduino_022.app/Contents/Resources/Java/libraries/

Any idea what's going on?

Well, getting a fresh install of Arduino seemed to clear it up.

Now that I'm up and running, my voltage output is -3.2v to +3.6v. I
thought the Octomod was supposed to output +/-5v?
