Presuming what's being referred to is the C++ implementation SourceForge 
here:

	http://sourceforge.net/projects/push-evolve/

I tried just now and it builds on CentOS 5.x without complaints, but at 
any rate the error is pretty obvious:  The right header is not being 
included to get `strdup`.  Checking the code, they're include <string>, 
which is an obsolete header in C++.  The correct header is <cstring> 
(which puts the functions in the `std` namespace, which they're already 
`using` in the source file).

Though the strange and arbitrary mixing of C strings and C++ 
std::strings is not promising for such a project in the first place.
