Build Fstar fails when using ./everest make.

[kgardas]

Hello,
following instructions and recommendations from ./everest check I've installed everything as needed and allowed ./everst script to do whatever it needed to do. Anyway, the build, e.g. ./everest make step fails with:

$ ./everest make

This happens for two last weeks at least even if I allowed ./everest pull to pull the latest.

The platform is solely installed Ubuntu 20.04 LTS VM.

When doing ./everest check, into which configuration file was the call to .opam/.../init.sh appended? Do you have more than one of .bash_profile, .profile, etc.?
