NetworkManager brings as dependency libmm-glib, and will install it in the same location as your custom built libmm-glib. The way to avoid this is to first install NM with the system-installed libmm-glib, and then you install your custom built libmm-glib on top. The libmm-glib is API/ABI compatible, so there is no risk of breaking NM by using a custom built library. -- Aleksander
