+Can anyone shed some light here?

+
+It looks like the implicit conversion from std::string to wxString isn't working.  That's used everywhere, the conversion needs to work.
+
+wxString is complicated by supporting win32's 16-bit wchar and 8-bit ansi dual-compile.  You can get that problem on Windows if the "unicode" (meaning wchar) build is used, so that wxString is wchar and std::string is char.
+
+It's probably some wxWidgets compile defines or build configuration.  What "configure" options did you use?
+
+I'm not sure __WXMAC__ is the right define.  It may be the Mac Classic support that's complicating wxString, and we only want OSX.  Try __WXOSX__ (or see below)
+
+http://docs.wxwidgets.org/stable/wx_cppconst.html
+"There are two wxWidgets ports to Mac OS. One of them, wxMac, exists in two versions: Classic and Carbon. The Classic version is the only one to work on Mac OS version 8. The Carbon version may be built either as CFM or Mach-O (binary format, like ELF) and the former may run under OS 9 while the latter only runs under OS X. Finally, there is a new Cocoa port which can only be used under OS X. To summarize:
+
+    * If you want to test for all Mac platforms, classic and OS X, you should test both __WXMAC__ and __WXCOCOA__.
+    * If you want to test for any GUI Mac port under OS X, use __WXOSX__.
+    * If you want to test for any port under Mac OS X, including, for example, wxGTK and also wxBase, use __DARWIN__"</div>
