Windows/Linux/Mac Eclipse plugin to compile and upload arduino sketches

First off, I want to say - stellar job man! I am digging this! I have been trying to get Eclipse working for Arduino on and off for a while now.

I am game to be a tester for OS X.

Thus far, all is well. All but:

**** Build of configuration Release for project Arduino_test_002 ****

make all 
Building file: ../Arduino_test_002.cpp
Invoking: AVR C++ Compiler
avr-g++ -I"/Applications/Arduino.app/Contents/Resources/Java/hardware/arduino/cores/arduino" -I"/Users/nick/Documents/Home_Workspace/Arduino_test_002" -D__IN_ECLIPSE__=1 -DARDUINO=22 -Wall -Os -ffunction-sections -fdata-sections -fno-exceptions -g -mmcu=atmega328p -DF_CPU=16000000UL -MMD -MP -MF"Arduino_test_002.d" -MT"Arduino_test_002.d" -c -o "Arduino_test_002.o" "../Arduino_test_002.cpp"
/bin/sh: avr-g++: command not found
make: *** [Arduino_test_002.o] Error 127

**** Build Finished ****

avr-g++ is not being found. I have no idea why though. avr-g++ is readily available on my $PATH.

Even more confusing, is when I have an AVR project, it sees and uses avr-gcc just fine.

Anyone have any clue to this?

Thanks in advance.
