bio-core and bio-core-ext are versioned and have *versioned*
dependencies. I.e. each included gem has a fixed version. That is
exactly what we want, so we can support users.  You don't want every
user to have different combinations of gems. No way we can
troubleshoot the latter!

This way we can also pull the consistent case for testing through
buildbot!  That is we test current releases of bioruby and two
meta-packages - just need a script to unpack them and run the tests.

For biogems individually we can test the last revision on the master
branch of each github repo. Which is a good thing too, because that is
what users resort to, if the meta-gem is not up-to-date enough.
Obviously, we don't *support* that. It is a risk the user is taking.
Any issues he'll have to resolve with the maintainer of the gem.
