See Juliusz Chroboczek's page for further information. Porting instructions for FreeBSD can be found at Stephen Montgomery's software page . A program called ttf2bdf can produce BDF files suitable for use in an X environment from TrueType files. For people requiring the use of Asian TrueType fonts, the XTT font server may be worth a look. The FreeType Projects page is a good starting point for information on these and other free TrueType projects.
Many fonts are available on the Internet.
They are either entirely free, or are share-ware. It would be good to have examples of using TrueType fonts with povray and ghostscript.
