DSSS on lib wiht import inside version

[Bill Baxter]

Hi,
I'm trying to make a dsss.conf for schooner.
Schooner can be built in two different flavors, one flavor using 
derelict for openGL, and another flavor using a built-in static 
translation of the OpenGL headers.  To that end some of the Schooner 
libraries use the following:
---------------
module gld;

version (useDerelict) {
   public import derelict.opengl.gl;
} else {
   public import gl;
}
...
---------------

When dsss tries to compile this library is fails to find gl.d.  I think 
perhaps the version statements are confusing it.

I suspect I could work around it if there were a way to explicitly force 
a depencdency in the dsss.conf, but I don't see such a thing.

Here's my current take at a dsss.conf for schooner:

-----
name = schooner

version(Posix) {
[x11]
buildflags+=-Ix11/source
exclude=x11/buildme.d
} else {
[win32]
buildflags+=-Iwin32/source
exclude=win32/buildme.d win32/source/win32/all.d
}

[freetype]
buildflags+=-Ifreetype/source
exclude=freetype/buildme.d freetype/build_freetype.d

[gl]
buildflags+=-Igl/source
exclude=gl/buildme.d

[gld]
buildflags+=-Igld/source
exclude=gld/buildme.d

[fonts]
buildflags+=-Ifonts/source
exclude=fonts/buildme.d

[*]
version(useDerelict) {
   buildflags+=-version=useDerelict
}
