$PATH and variable environment and Mosfet Theme ?

Hi ! I am really sorry about this topic, because I am sure that someone already replied before. I d'like just to know something : I have installed Mosfet Liquid 0.95 , but when I want to use this theme under KdeControlCenter, I got an error message that indicate a file is missing. At the end of the installation, it is wrote that the $PATH need to be changed (one more folder need to be present in $PATH) So, like SuSE 7.2, I edited the /etc/profile and put the folder, but that seems to do not work under SuSE 8.0. ($PATH is the same !) Do you have any suggestion to edit the $PATH ? Do you succeed to install Mosfet Liquid Theme ? Thanks
