sudo: port: command not found

First, you might need to edit your system's PATH

sudo vi /etc/paths

Add 2 following lines:

/opt/local/bin
/opt/local/sbin

Reboot your terminal

Make sure to delete ~/.bash_profile and ~/.bash_login so that .profile can work. This worked for me http://johnnywey.wordpress.com/2008/04/17/fixing-bash-profile-in-os-x/

You could try to source your profile file to update your environment:

$ source ~/.profile

I found the answer in the official website

$ vi ~/.profile

# add the following line
export PATH=/opt/local/bin:/opt/local/sbin:$PATH

And now restart the terminal or type source !$ (equivalent to source ~/.profile)

if you use zsh.please add flowing string to the line 'export PATH="..."' in file '~/.zshrc'

:/opt/local/bin:/opt/local/sbin
