Dan (Gerald): can you cd to amber20_src/build/AmberTools/src/cpptraj/src/
and type "ldd"? Does it point to a miniconda libstdc++? On
my Ubunutu machines, it points to the libstdc++ in /usr/lib.

pytraj seems to work fine on Gerald's Fedora container, so maybe seeing what
ldd reports there might be a start.
