Hi, openfortivpn 1.17.3, the current version in master, stopped building for me after guix pull, it seems stuck on building ppp-2.4.9. 

Please take a look at my patch from 10 months ago, issue 73450, which updates openfortivpn so that the current ppp can be used, that seems to fix the problem that is now present.

Thanks!
