Cross building ports

[M. Warner Losh]

Greetings,

Many moons ago, I took a look at the ports system and concluded that
doing cross builds on ports would be difficult.  However, I have a
need now to build FreeBSD/arm ports on a FreeBSD/i386 or FreeBSD/amd64
box.  Before I dive into this problem again, I thought I'd see if
anybody can share their experiences and thoughts on the matter.
Thanks much...

Warner
