My guess is that you are not linking against the system version of libiconv, but against a version of that library compiled by a third party (fink, macports, ...). That is not supported by the cwstring unit (and it's a good thing that gives an error at link time, since the program would otherwise fail to start on machines that do not have that custom version of libiconv installed).

I think you should be able to force the linker to pick the system version by passing -k/usr/lib/libiconv.dylib on the command line. Alternatively, remove the fink/macports/... directory from your linker search path (in case you don't use any of its libraries).
