Here is the dmd.conf search path (as documented on 
http://www.digitalmars.com/d/dcompiler.html):

1. current working directory
2. $HOME
3. the directory the dmd executable is in
4. /etc/dmd.conf

If you simply extracted the dmd archive into /opt, then it will find the 
dmd.conf file alongside the binary before it finds the one at 
/etc/dmd.conf. Either remove the one next to the binary or edit it.
