texmacs on 6.2

Hello,

I have probably a trivial (user) question.

I've used texmacs on 6.1, amd64.
Now I wanted to install it on 6.2, i386, but I can
neither find a package nor i386 is mentioned
among Archs in ports (the same for amd64, btw.).

What can I do?
Why isn't i386 and amd64 available?

Thanks
Ruda
