dev-ruby/rspec-its missing ~> rake-10.1.0 dependency

[GoogleCodeExporter]

Note: this is bottom priority, from bleeding-edge operation.

Neither the Pentoo or Gentoo tree has rake-10.1.x, but the rspec-its package 
(all versions) has an internal dependency on it (see 
https://github.com/rspec/rspec-its/blob/master/rspec-its.gemspec).

Where this affects Pentoo is that pentoo/pentoo-exploit pulls in www-apps/beef, 
which through a dependency on dev-ruby/em-websocket eventually depends on 
dev-ruby/rspec-its.  This breaks updates in an easily-solved "--keep-going" 
manner.

Specifically it appears that dev-ruby/em-websocket-0.5.x introduces this 
dependency tree, so sticking with the 0.3.x branch by masking makes for a 
"cleaner" fix.
