install or download port collection?

[Paul Darius]

hi there,

i just new to fbsd and rpi.

the fbsd image downloaded from
ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/arm/armv6/ISO-IMAGES/10.0/FreeBSD-10.0-STABLE-arm-armv6-RPI-B-20140427-r265018.img.bz2
and the image successfully dd into sdcard 32GB.

surprise that I can not find sysinstall, but at the end I find bsdinstall
question is, how to install or download the port collections ?
i try using ftp and http direct but no luck
