--- Comment #6 from Andy Mender andymenderunix@gmail.com ---
I double-checked and I discovered that present uses a v2 feature of mistune (AST renderer). And upgrading to v2 fedora-wide would break python-m2r and python-nbconvert. A compat package is definitely needed...
I found these compat packages: https://src.fedoraproject.org/rpms/compat-gdbm https://src.fedoraproject.org/rpms/compat-flex
Sadly, a lot of the compat packages were already retired years ago so their format might not be correct.
