some compilers (like Darwin's gcc-4) will attempt to locate a shared library in the lib search path before searching for a static one ... the default behavior of gcc on linux is to search all library paths for static or shared versions of a library and use whichever it finds first (defaulting to shared if a path contains both static and shared)
so, doing '-L./lib/readline -lreadline' on Darwin will have the compiler search ./lib/readline then the system paths looking for a shared version of libreadline ... if it fails, it restarts looking for a static lib. gcc would find libreadline.a in ./lib/readline first and just use that. who knows what different compilers do :). find attached a patch that will cause the build system to do -lreadline if building against the system readline or use ./lib/readline/libreadline.a if building against the included version ... no complications this way -mike
