Not that I know. The OSX installers on python.org include more C libraries, but not everything. The script that creates those installers is in the repository and it should be easy enough to enhance that to include more libraries. >>>>> >>>> readline requires an external library or python 2.6.5, 2.7 or 3.2. >>>> >>> Hmm...

One other thing: the OSX linker looks for dynamic libraries all along its search path before looking for static libraries, you have to add " -search_paths_first" to LDFLAGS if you have static libraries that you want to link to which may also be on the system. BTW. If you don't mind getting libedit instead of GNU readline run configure with 'MACOSX_DEPLOYMENT_TARGET=10.5' (or 10.6) in the shell environment. The resulting binary will require OSX 10.5 and setup.py will then use the readline emulation in the system library 'libedit' (it won't do so with the default options because that generates a binary that runs on 10.3.9 or 10.4 and those don't have a good enough libedit library). Libedit is a BSD library that offers simular functionality to GNU readline, but using a different C API and a different configuration.
