the hdf5 error is bizarre. I've just tried restarting the build, so we'll see where that goes.

[ljwolf]

note that the hdf4/5 libraries are coming from conda-forge.

I think what we want is to append this to the config:
conda config --append channels conda-forge
so that only packages that aren't in conda are grabbed from conda forge.

[ljwolf]

Also, do you know what, exactly, we need from the forge? if so, we could just grab that only with a separate conda install -c conda-forge

[slumnitz]

Ok thank you, I can try and see what I can do about the conda-forge issues. Additionally I found this: conda-forge/geopandas-feedstock#28. I'll look into it later, it seems like the fix needs a bit of trial and error :)

[slumnitz]

It is still failing :( It seems to be this issue: conda-forge/fiona-feedstock#82. The conda-forge team is working on it at the moment.

[slumnitz]

@ljwolf all working now. :)

[sjsrey]

This looks good to me.
