Please find attached a patch to get Password Safe 3.23 to compile on Mac OS X 10.6.
compiles against the wxWidgets library version 2.8 that is present in Mac OS X 10.6.
as only the debug libraries are present, only the debug target compiles (this should be fixed by compiling against a custom-built wxwidgets library)
password databases can't be closed, because of a crash: [Debug] 23:29:01: /Users/me/pwsafe-3.23-src/Xcode/../src/ui/wxWidgets/guiinfo.cpp(91): assert "!wxString(m_treeSelection).IsEmpty()" failed in SaveTreeViewInfo().
it compiles for ppc and i386 in 32-bit mode, but ppc has not been tested.
