Are you saying that just building gdal without configuring options means
there is no proj support in gdal, and that you have to give an
affirmative --with-proj?  I didn't guess that, as usually configure
finds things that are wanted normally.

I read
  https://trac.osgeo.org/gdal/wiki/BuildingOnUnix
and I don't see this mentioned.

I wonder what the "dynamic" output (the beginning of the proj part in
configure.ac) means then.


Thanks for the hint - I will add --with-proj and see how that goes.
