Linux binaries were downloaded?

Today i’ve updated my gmod server and saw some .so binaries that looks like linux binaries

28.11% downloading ./orangebox\garrysmod\bin\lua_shared.so

34.04% downloading ./orangebox\garrysmod\bin\scenecacheproxy.so

77.51% downloading ./orangebox\garrysmod\bin\server.so

87.71% downloading ./orangebox\garrysmod\bin oybox.so
P.S Ok. So install manual on wiki was changed. No more stupid Wine&Xvfb hax needed.
