Too much dependencies for gegl

[David DEMELIER <demelier.david%gmail.com@localhost>]

Hi there

I was surprised when I tried to install gimp on NetBSD, when
graphics/gegl starts I noticed that it took many time. The problem is
the number of dependencies of it:

in gegl make build-depends-list show that:
