I've now tried it with the following two combos:

OS       Compiler     Boost Version   Phoenix Version
windows  vc8          1_41_0          0x2000
linux    g++_4.3.2    1_39_0          0x2000

Works fine for me. I only have gcc_4.3.2 on the virtual machine
I was using. I'll reboot into linux later and check 4.4.2...
but meanwhile, can you paste the error that you get with
your setup and the source above?
