Dear Marco, There is no port or package for tex4ht and it is not included in teTeX which FreeBSD uses. You have to visit the web page of tex4ht to download it and you need to compile it manually.
I don't think it will be enabled even if you install lyx-1.6, but the (unauthorized) port of lyx-1.6 itself can be downloaded from: http://www.int.otaru-uc.ac.jp/lyx-howto/install/port-lyx-1.6.2.tar.bz2 Please expand it in /usr/ports/print and make it. LyX 1.6 will not be introduced in system ports until the overhaul of LaTeX system in FreeBSD completes (which is taking time somehow). Koji
