I have a simple Spirit parser program which won't compile. I am running boost 1_42_0 with gcc on a mac. The code and error message are attached.

I hope you can tell me two things: first, what have I done wrong, and second (if necessary), how can I figure out what I've done wrong from the error message.

First, you missed to include #include which is necessary to make std::pair a fusion sequence. Second, after adding this it still fails to compile as you're trying to use this std::pair as the attribute for an 'alnum >> alnum' parser, which exposes a tuple and your attribute is not compatible with this (you can't directly construct a string from a single char).
