How far off is number 1?

I presume this means I am not able to compile and run 32bit apps currently?

One of the apps I am interested may not be 64bit clean. In Gentoo I had 
to enter the 32bit dev environment to compile it. I haven't been able to 
do that successfully on Gentoo yet. That is one of the reasons I went 
exploring FreeBSD. Not the only one tho'. :)

Actually if FreeBSD AMD64 was tier 1 when I got my machine I may have 
never tried the Gentoo port.

Gentoo AMD64 has mozilla running.

Gentoo AMD64 is using gcc 3.3.2.

I don't know if any of the Gentoo AMD64 work towards mozilla is of any 
benefit to FreeBSD or not. I am not a C/C++ programmer. :)
