The correct one is pretty much wherever you want to put them. It's just that 
you have to put it in dmd.conf. As to your problem, I see three issues right 
off the bat:

1. You're resetting DFLAGS, not appending to it. Notice that the only import 
path listed in your error is the second one. The first one got overwritten. I'd 
suggest just putting it all on one line.

2. I don't know why you're listing two locations for Phobos anyway. You need
a -I to point to where the Phobos src is located, and there's only one set. -I 
needs to point to whatever directory std and etc are in order for the compiler 
to find Phobos.

3. You're missing druntime's import files (hence the error, since that's where 
object.di is). So, you need a -I flag pointing to druntime's import directory.

However, if you're not going to use your package manager to install dmd, I'd 
suggest that you just download the zip file, unzip it somewhere on your box, 
and add its linux/bin directory to your PATH. If you do that, it should all 
just work.
