I guess I need to check which ports use which shared libraries, using pkg?
So maybe I don't need WITHOUT_ICONV in /etc/src.conf ?
Maybe base iconv could be enhanced to be identical to the port, by adding wchar_t support?
I like Lev Serebryakov's idea of a notice in UPDATING, and would add that such a notice on possible iconv conflicts could be added tp UPDATING for both the ports tree and system-source tree.
