Constraint logic programming is one of the most attractive research areas in logic programming. Due to (J. Jaffar, 1987) the theoretical foundation of a general constraint logic programming language scheme CLP({{$\cal X$}}) is available. Unfortunately, implementing a CLP({{$\cal X$}}) system for some domain {$\cal X$} is a difficult task. The problematic points are providing a {\it constraint solver} and ensuring the {\it incrementality} of the constraint system. We propose here to use an existing CLP system as implementation environment for a new CLP language. We show that under certain conditions we can use the given constraint solver as constraint solver for the new CLP-language. We focus here on prototyping CLP({{$\cal PB$}}), where {$\cal PB$} denotes the structure of pseudo-Boolean functions, in CLP({{$\cal R$}}), where {$\cal R$} denotes the structures of real numbers.
