+    This fomula requires that boost formula gets built with '--with-icu'
+    option. If not, link will fail.
+
+    If in doubt, try uninstalling boost (brew uninstall boost) and
+    installint with ICU support (brew install --with-icu boost). For
+    that you will also need icu4c installed (brew install icu4c).
