Help with Eclipse setup

I followed in Eclipse instructions found here: Using Eclipse with Arduino Duemilanove - Chipkin Automation Systems. I'm using Arduino 0018, WinAVR 20100110, AVR Plug-in 2.3.4, Eclipse 20100917-0705 and Windows XP SP3. When I try to build the example project I get error 258. I went to the console tab and this is what it had:

Building target: Blink 11-10.elf
Invoking: AVR C++ Linker
avr-gcc --cref -s -Os -o"Blink 11-10.elf"  ./main.o   -lArduinoCore -lm -Wl,-Map,Blink 11-10.map,--cref -L"C:\Documents and Settings\Scott\My Documents\Arduino\Eclipse\ArduinoCore\Release\" -mmcu=atmega328
"C:/Program Files/WinAVR/utils/bin/sh.exe": -c: line 1: unexpected EOF while looking for matching `"'
"C:/Program Files/WinAVR/utils/bin/sh.exe": -c: line 2: syntax error: unexpected end of file
make: *** [Blink 11-10.elf] Error 258

It appears there is a problem with WinAVR/utils/bin/sh.exe, but I have no idea how to resolve this. I tried reinstalling WinAVR, but this didn't fix the error. Any suggestions?
