Hello,
the path to modules can be specified via command line option -L or cfg parameter loadpath (aliased as mpath for K backward compat). loadpath overwrites the value given by -L.
The question is whether the value given via -L shouldn't be effective all the time (i.e., loadpath cfg parameter ignored when -L is given) since it is via command line parameter -- my expectation is command line options should have higher priority. Changing it now will break backward compatibility (if anyone used it like now) while in testing, but if all think is a bug, then can be fixed.
Cheers, Daniel
