おそらく問題なのは、下記のエラーだと推測する。

make install
/usr/bin/install -c -o root -g wheel -m 0755 tmailscanner.so /home/littlebuddha/local/lib/ruby/gem/gems/tmail-1.2.2/lib
install: /home/littlebuddha/local/lib/ruby/gem/gems/tmail-1.2.2/lib/tmailscanner.so: chown/chgrp: Operation not permitted
*** Error code 71

しかし、Tmail の setup.rb には下記の記述がある。解決するには、root 権限が必要になるのだろうか？

# @all@ and @install@ may require root privileges.
