+- Since rubygems 2.5.0 the default version in the gem bin stub
+  changed from '>= 0' to '>= 0.a'. This was done to allow
+  prerelease versions. Our patching script didn't take the '.a'
+  into account and generated version fields like '= 0.10.1.a'
+  instead of the expected '= 0.10.1'. This fix accounts for the
+  '.a'.
