[DRE-maint] liboauth-ruby: initial upload for review

[Will Daniels]

Hello,

I have uploaded a new package liboauth-ruby for somebody to review
please. This is my first attempt, so be kind :P

A few notes:

1. I did not add a ruby 1.9.1 package because it depends on libhmac-ruby
which doesn't appear to have one yet.

2. I was not entirely sure what to do with the tests, namely whether to
package them along with the lib or the docs, or where in the rules to
run them in the build. I ran them locally and it all seems to work fine,
but aside from that I have ditched them for now :$

3. The upstream sources include scripts to generate the lib's homepage
on rubyforge. I did not think it of value to attempt to package this for
docs or anything else. For starters, it begins with instructions to
"sudo gem install oauth" etc.

4. I get some warnings during build, while generating the rdoc, like this:

(process:3567): Pango-WARNING **: error opening config file
'/root/.pangorc': Permission denied

I think it has to do with graphviz generating it's diagrams, perhaps
looking for some fonts or screen metrics?. It seems harmless enough in
that the diagrams look fine to me, but perhaps one of you knows
differently? Or maybe someone knows how to suppress that cleanly?

All feedback gratefully received.

Cheers,
Will
