Yes. Do a CVS checkout of the current source tree. The std C++ lib on 
MacOS X does not include definitions of specializations of char_traits 
for anything other than char, and there are places in ZooLib where 
we're using 16 and 32 bit code units (depending on your compiler 
settings one or other may be a wchar_t). I think that the necessary 
code might even be in the 0.9 release, but just isn't switched on when 
building gcc/mach for macos X.

A+
