This would be a slight problem for me (FreeBSD) - as the builds are
usually done on the user's system. However, I think it is probably OK
to add rubygems as a build dependency.
The process a FreeBSD port works by on install is
* download the archive from the original developer
* extract the archive into work/<portname> in the ports dir (can be other
* do any patches inside work dir
* do build inside work dir
* do install directly into main space
* register install into the local package database
* (optionally) Generate a binary package for use on other machines.
Most cases do NOT include the last stage, though. Remote-built packages
are usually used only for first-time installs.

This is also required for FreeBSD. Some specific requirements for a
Respects DESTDIR - a prefix to install under, not counted as part of the
logical install paths. That would be /tmp/packagename in the above
Respects PREFIX - this is where to install into, as counted by the
package internally. Defaults to /usr/local.
Respects LOCALBASE - this is where to get dependencies from.
Respects directory layout under PREFIX. This include (but is not
bin/ - binaries for execution by the user
etc/ - configuration files
etc/rc.d/ - startup files for daemons
lib/ - libraries (platform specific, but we're somewhat lax about that)
libexec/ - daemons
man/ - man pages
share/ - stuff that can be shared between architectures, but we're
somewhat lax on it. However, we're not lax on:
share/examples/<packagename> - examples for this package
share/doc/<packagename> - documentation for this package
There's probably some more, but these are the ones that are off the top
of my head.
I'll be back with more info later; I just thought I'd add a quick
overview of the main stuff right here and now.
