Actually it is finding the library because some of the error messages
reference objects in it.  Something goes wrong with finding some of
the symbols in it, such as some from `json_value.cpp`.
What is the output of?

    $ ar t Utilities/cmjsoncpp/libcmjsoncpp.a

I don't have access to this platform so hopefully someone else can dig
into it further.  Perhaps some preprocessing differences cause symbol
mangling to be different across sources.
