OSX Builds in travis are failing (timeout?) at installing HDF5. On my mac laptop it's taking over 1hr to build HDF5. We will need to find a way to keep travis not timeout in order to complete osx build successfully.

I remember Travis announced reduction of Mac machines for open-source projects because of their high cost, so anyway many builds now fail while waiting for a slot to run. Let's keep .travis as is then.

Thanks for updating the package!
