Why are you using NO_DEFAULT_PATH and but listing /usr/bin and  
/usr/local/bin? This is wrong and breaks "/usr/local/bin before  
/usr/bin". Just drop those from the list and also your  
NO_DEFAULT_PATH. If you want your list first, use HINTS instead of  
PATHS.
Additionally, you may want to mark the found values as advanced (like  
it was before).
