Bug 877651 – app-admin/conserver-8.2.6-r3: does not always need net-libs/libnsl

• Product: Gentoo Linux
• Status: UNCONFIRMED ---

[Description Jocelyn Mayer 2022-10-19 13:31:10 UTC]

It appears that libnsl is an indirect dependency which is only required when using tcp-wrappers and tcp-wrappers have been compiled with the netgroups USE flag enabled.

Reproducible: Always

Steps to Reproduce:
1. Compile tcp-wrappers without netgroups USE flag set
2. Compile conserver
3. Check runtime libraries dependencies /lib64/libwrap.so.* and /usr/bin/conserver using ldd -r -d
Actual Results:  
ldd shows that neither tcp-wrappers nor conserver are actually using libnsl.
This is OK for tcp-wrappers as libnsl dependency depends on netgroups USE flag (in RDEPEND). But conserver ebuild keeps a dependency only this library.

Expected Results:  
There should not be any dependency on libnsl when tcp-wrappers was compiled without netgroups USE flag set

Making the net-libs/libnsl conditional in conserver ebuild made me able to distclean this library I don't have any usage, not using NIS on any machine.

Patch to conserver ebuild, making libnsl dependency optional

Adding a netgroups USE flag to conserver and requesting this flag to be set the same way for tcp-wrappers makes possible to libnsl dependency depend on tcpd and netgroups USE flags set together

output from emerge --info =app-admin/conserver-8.2.6-r3

Here is the emerge --info output _after_ patching the ebuild and re-merging it.
