dsss implements a pragma(link,...) which does basically that.
It's really what pragma(lib,...) should have been to begin with.

From
http://svn.dsource.org/projects/dsss/trunk/docs/README.software_engineers
"""
The -ll flag is only useful for explicitly linking libraries into 
binaries. If the DSSS-implemented library depends on a non-DSSS library, 
the dependency must be specified in a .d file which is part of the 
DSSS-implemented library. This is done with the 'link' pragma, which 
must always be specified within version(build):

version (build) {
     pragma(link, "example");
}

The above example will cause any binary linked against the 
DSSS-implemented library to link against the library named libexample.a 
(or example.lib on Windows).
