迁移到雪豹搞砸了我的红宝石路径

Question

自从我从Leopard迁移到Snow Leopard后,我得到了

$ ruby script/server 
Rails requires RubyGems >= 1.3.2. Please install RubyGems and try again: http://rubygems.rubyforge.org

使它工作的唯一方法是:

$ /usr/bin/ruby script/server
=> Booting Mongrel
=> Rails 2.3.8 application starting on http://0.0.0.0:3000

所以我想我的路径被破坏了,这是我的〜/ .profile文件fyi:

##
# DELUXE-USR-LOCAL-BIN-INSERT
# (do not remove this comment)
##
echo $PATH | grep -q -s "/usr/local/bin"
if [ $? -eq 1 ] ; then
    PATH=$PATH:/usr/local/bin
    export PATH
fi

export PATH=$PATH:/opt/local/bin
export MANPATH=$MANPATH:/opt/local/share/man
export INFOPATH=$INFOPATH:/opt/local/share/info

PATH="/usr/local/mysql/bin:$PATH"
PATH="/opt/local/bin:/opt/local/sbin:$PATH"
PATH="/usr/local/bin:/usr/local/sbin:$PATH"
export PATH

export GEMDIR=`gem env gemdir`

我怎样才能解决这个问题？
