Description Ivan Diorditsa 2023-04-21 11:56:42 UTC 
when I emerge net-dialup/ppp-2.4.9-r8 with -ipv6 flag, the ipv6 disabled and pppd/ipv6cp.c does not compile. However pppd/plugins/pppol2tp/pppol2tp.c still adds the ipv6_up_notifier (which is not provided due to ipv6cp.c is not part of compilation now).

This results in pppol2tp.so never loading as loader cannot resolve the symbol ipv6_up_notifier

Reproducible: Always

Steps to Reproduce:
1. emerge ppp with -ipv6
2. run pppd and load the pppol2tp.so plugin
3.
Actual Results:  
2023-04-21T11:40:12.22783 /usr/sbin/pppd: /usr/lib64/pppd/2.4.9/pppol2tp.so: undefined symbol: ipv6_up_notifier
2023-04-21T11:40:12.22787 /usr/sbin/pppd: Couldn't load plugin pppol2tp.so

Expected Results:  
pppol2tp plugin can load successfully

We are dropping the IPv6 USE flag in ppp-2.5.0 anyway.
