Sure.. but note that I'm be on vacation for 3 weeks starting on sunday -
so it's note rudeness if I don't answer my mails in the coming weeks ;-)

Still, I debugged this further, and though I's share the results, even
if you don't have time at the moment.

"otool -t -v ~/Installs/wxMac/2.7.0/lib/libwx_base_carbonu-2.7.a | grep
mb_str | c++filt"
gives:
wxString::mb_str(wxMBConv const&) const

Note that additional "const" flag for the wxMBConv argument. I never
knew that const-modifiers are recorded in c++ mangled names - but
it seems they are, and it seems that this is causing the trouble..

I've absolutly no idea yet why c++ uses the signature including "const"
when compiling wx, but the one without "const" when linking against it...

My build server is still running 10.3.9, btw, with gcc 3.3 - so I guess
it's this version of gcc causing the trouble..

Cool! How did you archive that?
