Maybe that was an artifact of something … but:

Does it enter via libcurl, perhaps? I'm rebuilding it without psl now
on this install … then netcdf, and indeed, it's gone. Stupid libtool
linking in indirectly needed shared libs. Maybe I should put
--as-needed into LDFLAGS. The libtool archive of curl should've put
them as private libs for static linking only anyway. But then, clean
minimal library deps are not of such great value when I don't
update/change packages in a tree once installed.

So yes, You can ignore this patch. It was a pure artifact of curl
bringing in libpsl before.


Alrighty then,

Thomas
