As pointed out in #42 (thanks @chiastolite!), rspectre uses features from parser that are only available in 2.5 (see #21). The APIs that are in use should also be compatible with 3.x and because parser is intended to have a permanently stable API (or, as close to that as possible), this can just be changed to >= 2.5 for now.
