FreeBSD Ports Tricks
BSD Forums writes "One of FreeBSD's biggest benefits is its ports collection. You can go years without learning more than just make install clean, but there are dozens of features built into the ports tools. OnLamp's Dru Lavigne demonstrates several of these tricks to simplify your life."
From http://www.freebsd.org/doc/en_US.ISO8859-1/books/h andbook/linuxemu.html , actually it can in fact run quite a few Linux applications.
"In a nutshell, the compatibility allows FreeBSD users to run about 90% of all Linux applications without modification. This includes applications such as Star Office, the Linux version of Netscape, Adobe Acrobat, RealPlayer 5 and 7, VMWare, Oracle, WordPerfect, Doom, Quake, and more. It is also reported that in some situations, Linux binaries perform better on FreeBSD than they do under Linux."

Check it out. Start with the manual page (man portupgrade) after you install it, then use Google for more info. It's well worth it.
