This is what DUB executes (when you build a project depending on 
vibe.d) via dub build --rdmd (I've replaced absolute path to the 
project with <path> and added newlines for clarity):

rdmd --build-only --compiler=dmd -w -g -debug
-version=LIBEV4
-version=VibeLibeventDriver
-version=Have_vibe_d
-I<path>\source
-I<path>\.dub\packages\vibe-d\import
-I<path>\.dub\packages\vibe-d\source
-J<path>\views
<path>\.dub\packages\vibe-d\lib\win-i386\eay.lib
<path>\.dub\packages\vibe-d\lib\win-i386\ssl.lib
<path>\.dub\packages\vibe-d\lib\win-i386\event2.lib
wsock32.lib
ws2_32.lib
-ofgamesrv.exe
source\app.d

So it seems you're missing wsock32.lib, but I'm a bit puzzled 
with linker errors, as those missing symbols are not inside 
wsock32.lib..

Sorry I couldn't be of more help (I'm new to vibe also, but 
luckily haven't hit any major build issues like you did).
