Conda issues with cdat channel

[durack1]

Hi folks, apologies if this is already known, but I just tried to install the latest official CDAT and managed to hit many nasty errors, wondering if I am doing something wrong, or whether there is actually an issue:

(base) trustym:~ paul$ conda create -n cdat81py2 -c conda-forge -c cdat cdat "python<3"
