May be this is the problem. There should be only one PATH. It is inherited from the parent process. It is possible that the parents have different paths. To check this you could start LyX from the same terminal that you ran maple from (which you said succeeded), as opposed to starting LyX from a menu which would lead to a different parent. I don't think I'm going to be of much help since I only use Maxima. Good luck, Scott
