If you can't find a pre-compiled version of boost using the package manager of your choice, you can always download the source code and compile it yourself:

If you're only going to do simple matching, with stable patterns, writing your own matcher isn't extremely hard.

The result is a state machine that do transitions using the next character in the string you're matching against.
