Upon installing macports on my OSX machine I found that I come across the following error:

port: command not found

Well upon doing a quick search of I found my answer.

nano ~/.bash_profile

#paste the following:
export PATH=$PATH:/opt/local/bin
export MANPATH=$MANPATH:/opt/local/share/man
export INFOPATH=$INFOPATH:/opt/local/share/info
Ctrl+O
Enter
Ctrl+X

Now just reload terminal and everything should work like a charm. I newb proofed this article for the sake of those users who have not used the nano editor.
