===> Installing for ruby-2.0.0.576_1,1パッケージの更新情報を確認すると、以下のような作業が必要なようです。
===> Checking if ruby already installed
===> An older version of ruby is already installed (ruby-1.9.3.547_3,1)
You may wish to ``make deinstall'' and install this port again
by ``make reinstall'' to upgrade it properly.
If you really wish to overwrite the old port of ruby
without deleting it first, set the variable "FORCE_PKG_REGISTER"
in your environment or the "make install" command line.
# pkg updating

20141008:portupgradeを利用しているので上記の4行を実行したところ、無事にアップデートすることができました。
AFFECTS: users of lang/ruby19
AUTHOR: swills@FreeBSD.org
The default ruby version has been updated from 1.9 to 2.0.
If you compile your own ports you may keep 1.9 as the default version by
adding the following lines to your /etc/make.conf file:
#
# Keep ruby 1.9 as default version
#
DEFAULT_VERSIONS+=ruby=1.9
If you wish to update to the new default version, you need to first stop any
software that uses ruby. Then, you will need to follow these steps, depending
upon how you manage your system.
If you use pkgng, simply upgrade:
# pkg upgrade
If you use portmaster, install new ruby, then rebuild all ports that depend
on ruby:
# portmaster -o lang/ruby20 lang/ruby19
# portmaster -R -r ruby-2.0
If you use portupgrade, install new ruby, then rebuild all ports that depend
on ruby:
# pkg delete -f ruby ruby-iconv portupgrade
# make -C /usr/ports/ports-mgmt/portupgrade install clean
# pkg set -o lang/ruby19:lang/ruby20
# portupgrade -x ruby-2.0.\* -fr lang/ruby20
このとき、パッケージの依存関係を見たくなったので、 /usr/ports/ports-mgmt/porttreeをインストールして利用しました。
