Title: Fix gemspec compatibility with old rubygems

Old rubygems versions (eg. 1.3.7) without this fix
https://github.com/rubygems/rubygems/commit/a2498af
don't like version numbers without a prefix.
As the gemspec specifies to be dependent on rubygems
1.3.5 we should fix this.
Also see https://github.com/rubygems/rubygems/pull/121
for discussion.

This should fix gh-674.
