All,
I'm building vxl version vxl-1.14.0 from source on OS X Mountain Lion, and I'm receiving the following error:

[ 77%] Building CXX object contrib/brl/bbas/brdb/CMakeFiles/brdb.dir/Templates/brdb_value_t+bool-.o
/Users/andi/Downloads/vxl-1.14.0/contrib/brl/bbas/brdb/Templates/brdb_value_t+bool-.cxx:3:1: error: explicit specialization of 'type_string_' after instantiation
BRDB_VALUE_INSTANTIATE(bool,"bool");


System:
OS X: Mountain lion 10.8.2
cmake: 2.8.9
llvm-gcc-4.2
llvm-g++-4.2
clang: 4.1
clang++: 4.1

Can anyone point me in the right direction about fixing this error. 

Thanks,
Andi
