Aaaand just a little reading of ruby.c leads us to:

ruby_init_loadpath(); initializes the $: variable ($LOAD_PATH). It
will be initialized with the content of the RUBYLIB  unix-environment
variable, plus the location of site_ruby and the current directory.
This path is searched whenever you invoke either require or load.
Therefore is ruby_init_loadpath very necessary if you plan to load
some modules.
