Bug#1066117: FTBFS: missing build-dep on libnsl-dev

[Aurelien Jarno]

Source: proftpd-dfsg
Version: 1.3.8.b+dfsg-1
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)
User: debian-glibc at lists.debian.org
Usertags: libnsl-dev

Dear maintainer,

Starting with glibc 2.31, support for NIS (libnsl library) has been
moved to a separate libnsl2 package. In order to allow a smooth
transition, a libnsl-dev has been added to the libc6-dev package.

This dependency has been temporarily dropped in the 2.37-15.1 NMU, as
part of the 64-bit time_t transition. This causes proftpd-dfsg to FTBFS in
sid with:

This can be fixed by adding an explicit Build-Depends on libnsl-dev.
