Commands do not work in xterm or terminal.

Hi I am having some issues with xterm and terminal. When typing in commands most do not work.

Here is an example:
more: Command not found.
man: Command not found.
ssh: Command not found.
emacs: command not found


Here is my path info from .profile
export PATH=/opt/local/bin:/usr/local/mysql/bin:/opt/local/sbin:/Library/Java/Home/bin $PATH
export MITSCHEME LIBRARYPATH=~/users/alosdiallo/Library/mit-scheme
export CLASSPATH=/Library/Java/Home/bin/

I also have a link from .bashrc to .profile
.bashrc -> .profile

Any Help would be greatly appreciated. Thank you
