ROOT is dynamically linked against glibc. If you experience errors like the following:
root: /lib64/libc.so.6: version `GLIBC_2.{some_old_version}' not found (required by /anaconda/envs/testenv/bin/../lib/libstdc++.so.6)
or
ImportError: anaconda/envs/testenv/lib/libPyROOT.so: ELF file OS ABI invalid
this means that you deployed ROOT on a machine with a very old glibc version, and you need to upgrade your distro.
