net-p2p/transmission-gtk2 fails to build

[Ruslan Mahmatkhanov]

Hi!

I'm trying to update transmission 2.13 -> 2.22 on 8-stable.

Errors like this:
../libtransmission/libtransmission.a(handshake.o)(.text+0x167d): In 
function `canRead':
/usr/ports/net-p2p/transmission-gtk2/work/transmission-2.22/libtransmission/handshake.c:789: 
undefined reference to `evbuffer_search'
../libtransmission/libtransmission.a(handshake.o)(.text+0x16d4):/usr/ports/net-p2p/transmission-gtk2/work/transmission-2.22/libtransmission/handshake.c:761: 
undefined reference to `evbuffer_get_length'

Full build log is here:
