I am having problem in loading dynamic libraries after I compiled root 5.20 and geant3 (downloaded via svn) successfully on my Mac. I noticed this is not a new problem, but I can not find the way to solve it. (With earlier root version, this problem did not show up)
In the following, you can find the error message and also the configuration of the system in detail.
