I don't know about the security risk mentioned by Herb:

Usually what I want is to put a directory either first or last in the  
path. (Herb is referring to having the current directory in the  
middle of the path.)

To do this (and/or include other directories) I use a script with the  
pathmunge function mentioned in http://tldp.org/LDP/Bash-Beginners- 
Guide/html/sect_11_02.html. Perhaps this could be of use to you too.

Best,
