Thank you.  That is helpful.  I had not picked up on the even/odd micro

That seems odd since the cairo and cairomm releases are both in the same 
directory: https://www.cairographics.org/releases/

OK, thanks.  We do have a minor problem.  We like to use stable 
releases.  Right now librsvg has released a 'stable' release that 
requires a cairo 'development' release (1.15.4).  I know that's not your 
problem, but we have decided to wait for cairo-1.16 and are wondering 
when to expect it.
