I think that the root issue is this sentence in lang/ruby22 Makefile:
@${RB_SET_CONF_VAR} "prefix" "ENV['PREFIX'] || \3"
It set the following in
/usr/local/lib/ruby/2.2/amd64-freebsd11/rbconfig.rb:
CONFIG["prefix"] = (ENV['PREFIX'] || TOPDIR || DESTDIR + "/usr/local")
That is wrong, as rbconfig.rb is sourced by gem infraestructure, and
therefore the result is dependent of your specific environment at
*runtime*.
