Yes, but gdal already depends on proj and not proj.4.
Then I examined the graph and did not find the offending package.
That's why I do not understand why gdal is recompiled.
I mean, let find the intersection between "guix graph gdal" and "guix
graph -t reverse-package proj.4", and I do not understand because I
find it empty.

I have try to replace proj.4 by proj in the inputs field and I get the
same error.
Well, it does not work for me. Maybe I am doing a mistake.
