It is OK to change the required deps as long as the program keeps working. Sometimes, however, we 
just add new ports for the specific desired versions of the dependencies (e.g., 
py37-sphinxcontrib-websupport11 and py37-sphinxcontrib-websupport).

If I understand correctly, HA is missing some runtime dependencies. Each runtime dependency should 
be specified (e.g., via RUN_DEPENDS).
