Description
The following two errors occurred when I tried to build boost 1.41 on gentoo with python 3.1. Complete log attached.

#4657 is a duplicate but contains a proposed patch. I'm thus closing this one as duplicate.
The main problem seems to be that PySys_SetArgv uses wchar_t while MPI uses char as the type for argv. Short of converting the string type of all arguments back and forth I don't see a reasonable solution.
