Bug#1130229: metview: FTBFS with libc6-dev dropping dependency on rpcsvc-proto

[Aurelien Jarno]

Source: metview
Version: 5.26.2-2
Severity: important
Tags: ftbfs
User: debian-glibc at lists.debian.org
Usertags: rpcsvc-proto

Dear maintainer(s),

Historically, the rpcgen has been provided by glibc. It was split out
into the rpcsvc-proto package starting with glibc 2.31 (released in
bookworm), and libc6-dev gained a dependency on it as part of the
transition.

It now makes sense to finish this transition by using an explicit
Build-Depends on rpcsvc-proto instead of relying on the dependency
pulled in via libc6-dev.

metview is one of the packages requiring this Build-Depends on
rpcsvc-proto. Indeed it FTBFS with a modified glibc that no longer
depends on it. From my build log:

Therefore could you please add a Build-Depends on rpcsvc-proto for the
next metview upload?
