Thank you, I will check that

I have

> export PATH=$PATH:$HOME/bin:/opt/local/bin:/opt/local/sbin:/opt/local/share/man:/usr/X11/bin


in my .bash_profile, but echo $PATH shows what you expected:

> dude at mac:~$ echo $PATH
> /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/dude/bin:/opt/local/bin:/opt/local/sbin...

ok, I have something new to work out.
