This indicates that the compiler was built on a system which had the
necessary pieces for the C++ runtime library to be configured with
--enable-clocale=3Dgnu (it will be used automatically if configure
detects it is supported)

Apparently on the system where it's installed something is missing.
Probably something in glibc, as Ian suggests.
