As far as I know, you still can't use pragma(lib,"") under linux.  It's  
only available in the windows version of dmd.

You have two options:

1) Add the following flag to the dmd command line:

   -L-lmysqlclient

2) use bud (build utility for d) and add the following to your source file:

   version(build) { pragma( link, libmysqlclient ); }

Number 2, I haven't tested on linux for awhile, so I'm not sure if it  
works.  But the build tool documents the availability of that feature.
