www/otrs is missing port misc/p5-Locale-Codes. The problem is revealed in a German environment when trying to add a customer, resulting in some internal server failure. The problem completely disappear when installing manually port misc/p5-Locale-Codes.
Well. Thanks for reporting this. However do you have any positive evidence indicating misc/p5-Locale-Codes is being *directly* used by otrs? Did you check the sources for "use" statement? What is your check modules output?
