installing Mango with DMD instead of ldc

[JJDuck via Digitalmars-d-learn]

Hello all,

I tried to install Mango and I found that it requires ldc. the 
makefile for Mango is from
http://svn.dsource.org/projects/mango/trunk/mango/build/ldc/makefile

I tried to install ldc on Windows but it doesn't go very smooth 
for the whole weekend, so I decide to try to install Mango with 
DMD.

I tried to change these two lines for start

DC=ldc   <--change to DMD
DFLAGS=-release -O -inline -oq -c    <----error at oq

I do not understand -oq and -c mean for ldc, and I cannot find 
anything from web.

Anyone who can assist me on this or is there a better 
alternatives to install Mango with DMD?

Thank you.
