You can use Pkg.pin() to force a certain package to a certain version.
Check out the second listing for pin() in the documentation here
<http://julia.readthedocs.org/en/latest/stdlib/pkg/#Base.Pkg.pin>.
As an example, I'm currently at HDF5 v0.4.4. I can pin it to v0.4.3 as
follows:
julia> Pkg.pin("HDF5", v"0.4.3")
INFO: Creating HDF5 branch pinned.4a2dff3b.tmp
INFO: No packages to install, update or remove
Note the v *before* the quotes; this uses the @v_str macro to construct a
VersionNumber object out of a string.
