Port xapian-bindings' dependency on MacPorts' (outdated) ruby port

[Marko Käning]

Hi,

I am trying to make use of xapian-bindings, which has a dependency on MacPorts'
ruby, which currently results in version 1.8.7 
---
$ ruby --version
ruby 1.8.7 (2013-06-27 patchlevel 374) [i686-darwin13]
---

Now I ask myself, whether this port deliberately asks for this old version, or
whether one perhaps could drop this dependency altogether, as I am obviously
having ruby installed natively in a much newer version on 10.9 and 10.10:
---
$ ruby --version
ruby 2.0.0p481 (2014-05-08 revision 45883) [universal.x86_64-darwin13]
---

Greets,
Marko
