Subject: Using gems from C extensions

Hello

I'm trying to use the json gem from a C extension. Doing this fails with
"no such file to load -- json (LoadError)":

    rb_require("rubygems");
    rb_require("json");

However, if I add

    rb_funcall(rb_mKernel, rb_intern("gem"), 1, rb_str_new2("json"));

before rb_require("json"), then it works fine. Is that how it's supposed
to work?

Thanks,
Andre
