I took the perl-Test-Harness dependency off automake (since Achim told 
me it was unneeded) around 21:00 UTC on the 03-05-2023

To me, it seems like both that, and an updated texinfo, were needed 
before installing cygport was possible, but I don't really understand why.

(There's definitely a problematic dependency chain cygport -> automake 
-> automake1.* -> texinfo -> versioned perl which we need to be aware of 
in future when rebuilding texinfo for updated perl)

I also noticed that the latest version of libsolv has a new API for 
getting the solver to explain it's decisions, so it might be nice at 
some stage to add some code to setup to use that and write what it says 
to the log (and then maybe go back and see what it says about the 
problematic circa).
