I've had the same problem recently. What I did was that I ran `dmd main.d 
-L-L/usr/lib/x86_64-linux-gnu/ -L-lcurl -v`. It would still fail to link, 
but I can find the linking command from the verbose output. It was 
something like this: `gcc main.o -o main -m64 -L/usr/lib/x86_64-linux-
gnu/ -lcurl -L/usr/lib/x86_64-linux-gnu -Xlinker --export-dynamic -
l:libphobos2.a -lpthread -lm -lrt`.
As you can see, -lcurl is there, but it still needs to be added again 
after -l:libphobos2.a. So just add it again so the command becomes:
`gcc main.o -o main -m64 -L/usr/lib/x86_64-linux-gnu/ -lcurl -L/usr/lib/
x86_64-linux-gnu -Xlinker --export-dynamic -l:libphobos2.a -lpthread -lm -
lrt -lcurl`. And it links and runs.
