I ran ldd on /lib/security/pam_env.so and didn't find any dependency on 
it.  Gdm does show a dependency on libpam.so.  I think PAM doesn't know 
about any of the programs that depend on it.  Instead, modules are 
written that other programs can access via libpam and libpam looks for a 
config file in /etc/pam.d.
