[Bug 1451419] [NEW] Plugin /usr/lib/pptpd/pptpd-logwtmp.so is for pppd version 2.4.5, this is 2.4.6

[Jonybat]

Public bug reported:

I have updated recently my system from utopic to vivid, and since that
moment pptpd stopped working.

>From what i understand, pptpd needs to be built against pppd version 2.4.6. This has been fixed in pptpd version 1.4.0-2, as reported here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=745770

I tested with the current pptpd stable package from Debian (1.4.0-5) and
it fixed the issue.
