You don't say what platform you are using, but I'll hazzard a guess that
it's Linux.

Did you use g++ to link the DLM? It's generally a wise thing to use the
same tool to create a shared object as you use to compile the source.

You could try linking the DLM with g++, or adding the the relevent c++
library to the link command - cerr is in one of the libraries called
/usr/lib/libstdc++..., the particular one depends on what version of g++
and libc you are using.
