At that point I suggest to reinstall eha, and/or do 'ldd' on its shared
library to find out what it thinks it is pointing to.  The 'threaded gemv'
must be coming from somewhere.

You may now have several R's on your system so you need to check your path.
Remember /usr/local generally wins so even if you have a self-compiled R and
a packaged on 'R' will probably get you /usr/local/bin/R.

We cannot tell. This is somewhat incomplete information. It appears to be
related to your computer.

You may be tired of me saying 'Docker' but it gives you a clean room, akin to
installing on a fresh empty machine.  Useful for debugging.
