I am honestly surprised that these worked (I haven't gotten around to testing for myself). I could have sworn there was a difference in how Continuum compiled python such that any binaries built against a stock python would not work in a conda environment. I ran into issues a couple years ago where a modwsgi package provided through yum wouldn't work with miniconda because of link-time differences.
I cannot for the life of me remember the error message, though.
