I just recently rebuilt Common C++ (1.2.5.1) for FreeBSD, and pre-built packages can be found at ftp://www.voxilla.org/pub/freebsd.  The only significent change recently made for FreeBSD is the use of "-pthread" as a link flag rather than implicitly linking lc_r.   This version is also in the FreeBSD ports collection and can be rebuilt from there, as well as being on the new 4.2 cdrom distribution.
