gvpe definitely isn't a fork of tinc, it merely uses tinc's
platform-specific tun/tap interface code (about 200 lines for
linux/kfreebsd).  the crypto code is completely different and in C++.

and unfortunately the embedded copy of libev is compiled with
EV_MULTIPLICITY set to 0 (libev in debian is compiled with the default
setting of 1), which changes the API/ABI.  (it controls whether an
additional parameter is required by function calls or passed to
