lang/gnat-glade uses
BUILD_DEPENDS= adagcc:${PORTSDIR}/lang/gnat
That should work.

As GNAT doesn't change often, I'd personally find
LIB_DEPENDS=gnat-3.15.1:${PORTSDIR}/lang/gnat (or whatever the path is)
fine: that's the version you have tested the port with, and that you
know it'll work with without changes.

You might offer an option to link libgnat statically, but I cannot tell
you how to do this with Ada code. If it's regular C linkage,
ld ... -static -lgnat -Bdynamic -lc ...
would do the job, where ... is a list of other linker objects,
libraries, whatever else goes into the executable of your port.
HTH,
