Trying to recollect what this was about: the BALLCore.sip
contains a sort of template which must be compiled by several
tools, the first being sip, before being usable by the python3
interpreter.  It is not built initially, due to a cmake file
using an old sip naming convention; see the first hunk in the
patch attached.

However, once the sip file is caught, the package fails to build
from source due to various errors in the generated code.  The
patch also addresses one of them in its second hunk.  I think I
was stuck on some "overrides" related errors, but they were
interleaved within sip output, I can send a proper log later
this week after an overnight build if needed.

Sorry I did not manage to go much further on that issue,
