Hello, I am a postdoc at Columbia University fairly new to yt and am having trouble installing it on the NASA Pleiades supercomputer. I was hoping that someone else has figured this out before and could help me. I tried running the yt install script obtained with: wget http://bitbucket.org/yt_analysis/yt/raw/stable/doc/install_script.sh When I attempt to run this script, it crashes giving the error message copied below. I believe it may be related to the version of ssl on Pleiades. Any help would be greatly appreciated. Thank you! Best, Eli Visbal ----------------------------------------------------------------- ...
