We keep c_lib separated because it has a separate build system. In gentoo the packages are built with "ebuild" which are building recipe. An ebuild has separate well defined phase for fetching, patching, configuring, compiling and installing. c_lib needs to be built before the python library. Configuring the python library currently comes after installing c_lib, we don't go back to a new configure phase after install there is only one such cycle in an ebuild. If you change the way c_lib is built by using the python library setup.py instead, we'll ditch our own separate package.
