This doesn't appear to work. The Travis builds fail with:

LoadError: UndefVarError: @compat not defined

while loading /home/travis/.julia/v0.4/HDF5/deps/build.jl, in expression starting on line 25

@tkelman, you have any idea what to do about this deprecation warning? I'll work on the concatenation warnings.

Dunno, I think people have just been living with this one.

Coverage decreased (-0.38%) to 72.22% when pulling 21aa76f on rened:dictfix into f011e58 on timholy:master.

Coverage remained the same at 72.6% when pulling 21aa76f on rened:dictfix into f011e58 on timholy:master.

I tried to reverse the order of @compat and @BinDeps.install - it seems to work now.

Very nice, thanks!
