ICU is an external dependency, we don't install it: it should already be 
installed prior to building Boost.

Further, if you are using one of the last couple of Boost releases, then 
Regex is a header only library, and there is no need to build and 
install anything.  You will however, have to link to ICU when you build 
your program.

With regard to not matching specific text, if you can post the actual 
test code, I'll look at it.
