Dear Achim,
Thanks for your message. I can reproduce the issue you describe on my
side. Even when defining the module-addpath procedure within the
modulefile.
>From a first quick analysis, it does not feel that this is the
indented behavior. I will need to investigate further down to find
what is going on.
Best regards,
Xavier
