hi, bjam cancels buidling in v1 and v2 mode on the latest cvs checkout. i used bjam built from the source from the checkout. error message said: Building Boost.Regex with the optional Unicode/ICU support disabled. Please refer to the Boost.Regex documentation for more information (and if you don't know what ICU is then you probably don't need it).
