Configure question about Wine / HAL

[Kris Moore]

I'm trying to get Wine to compile with HAL support on FreeBSD, and 
running into this error:
> checking dbus/dbus.h usability... yes
> checking dbus/dbus.h presence... yes
> checking for dbus/dbus.h... yes
> checking hal/libhal.h usability... yes
> checking hal/libhal.h presence... yes

> This is an error since --with-hal was requested.

What exactly is -ldbus-1? Is there a way around this? Configure is 
finding the dbus and hal headers properly, and they both work properly 
on the system.
