Comment (by RJVB):

 This looks like a visibility issue. With wxW 3.0.2.4:

 {{{
 nm
 /opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/lib/libwx_osx_cocoau_core-3.0.dylib
 | fgrep ModalDialogDelegate
 0000000000012af0 t -[ModalDialogDelegate code]
 0000000000012ad0 t -[ModalDialogDelegate finished]
 0000000000012a50 t -[ModalDialogDelegate init]
 0000000000012ab0 t -[ModalDialogDelegate setImplementation:]
 0000000000012b40 t -[ModalDialogDelegate
 sheetDidEnd:returnCode:contextInfo:]
 0000000000012b00 t -[ModalDialogDelegate waitForSheetToFinish]
 00000000003f7238 S _OBJC_CLASS_$_ModalDialogDelegate
 00000000003f70c0 S _OBJC_IVAR_$_ModalDialogDelegate.impl
 00000000003f70b8 S _OBJC_IVAR_$_ModalDialogDelegate.resultCode

 00000000003f7260 S _OBJC_METACLASS_$_ModalDialogDelegate
 }}}

 but with v3.0.3:

 {{{

 | fgrep ModalDialogDelegate

 }}}

 I'll check tomorrow if Audacity has an upstream fix but if not it may be
 necessary to fix this in wxWidgets. Can somebody please add Mojca to the
 CC list?
