databases/db4 broken on sparc?

[Hauke Fath <hauke%Espresso.Rhein-Neckar.DE@localhost>]

All,

since the last update, the databases/db4 pkg fails to configure on netbsd-4
with

[...]

(see pkg/43444). The package's maintainer appears to be busy elsewhere (or
does not have a sparc machine around), so I'll ask here: What is it that
sparc netbsd-4 is missing as opposed to, say, i386?
