There are two libraries using ICU - regex and locale

they look for the library in quite different manner as for Boost.Locale ICU
is central and important part. If you want to build Boost.Locale with specific
library location you should provide

   ./b2 -sICU_PATH=/path/to/icu/root

See:

    http://svn.boost.org/svn/boost/trunk/libs/locale/doc/html/building_boost_locale.html

I don't really know your specific setup and installation options
but the two last lines relate to Boost.Locale's ICU location and the
first one Boost.Regex's

Try to use this option and see if there any problems.
