The header files are there:
/usr/include/string.h and /usr/include/gcc/darwin/3.1/g++-v3/string
The string type is typedef'ed in the header file 
/usr/include/gcc/darwin/3.1/g++-v3/bits/stringfwd.h,
inside namespace std. Unfortunately, I am not familiar with namespaces, 
so my first attempts were unsuccessful.

I have now found out that if I insert

using namespace std;

early on in maple_filter.cc, then it compiles.

It will not work here, because I don't have a suitable version of maple, 
and I am not sure if such a version exists yet for Mac OSX. It is 
promised for the near future, and a command line version seems to be 
available somehow, but I haven't seen it yet.
