it's way easier, actually. first, you don't have to place files 
into correct directories if you are passing all of them (files) 
as arguments to dmd. they don't even have to have correct names. 
"correct" file placement is required only if dmd should search 
for modules on his own.

second: you simply didn't pass all the required modules. perf.d 
depends on core nanovg engine, but you didn't passed that to dmd.

the easiest way is just pall *all* *.d files you have to dmd. 
don't try to be picky ;-), dmd is fast enougth that you can 
safely pass alot of sources to it. and there is no harm in 
providing dmd with "extra" modules.


as for "correct" placement (if you want it), it should be like 
that:

dmd -Imodroot main.d
main.d is your main D file, modroot is dir where all modules will 
be. it should be like that:

modroot/arsd/color.d
modroot/arsd/<other Adam's modules here>
modroot/iv/nanovg/nanovg.d
modroot/iv/nanovg/<other NanoVG files here, keeping subdirs>


also, pref.d module is completely unnecessary, it is just utility 
thingy to show FPS counter. ;-)


p.s. you will also need stb_ttf port, arsd repo has it under the 
name "ttf.d".

p.p.s. the easiest way to do everything is this:
mkdir modroot
cd modroot
git clone git://repo.or.cz/iv.d.git iv
git clone https://github.com/adamdruppe/arsd.git arsd
cd ..
rdmd -Imodroot main.d
