It just maps
  ffi.load("GL")
to:
  dlopen("libGL.so", RTLD_LAZY|RTLD_LOCAL)

The FFI has no clue about the actual library paths on POSIX. It
simply relies on whatever dlopen() does, when called with a path
without a slash.

I was always under the impression dlopen() behavior is the same as
implicit dependency loading via ELF headers. Apparently I'm wrong.
Maybe have a look at readelf -d and at the various environment
variables related to the dynamic loader.
