Here's a little bug report. Don't know if it's my bad.

I'm running Ubuntu 12.04 (64-bit), compiler - DMD v2.063.2, DUB 
v0.9.17-29-g2be278a

I cloned the git repo (sha1 96a870e) and ran dub.

First-off, it complained about several 'cannot cast ulong to 
int'. I've fixed that with explicit casts.

Second, it complained about undefined reference to dlopen and 
friends. I've fixed that by adding
"libs": [
         "dl"
     ]
to package.json

And finally, I've got
object.Exception at src/rt/minfo.d(243): Aborting: Cycle detected 
between modules with ctors/dtors:
dchip.cpPolyShape -> dchip.chipmunk_private -> dchip.cpArbiter -> 
dchip.cpSpace -> dchip.cpSpaceStep -> dchip.cpCollision -> 
dchip.cpPolyShape

Which I don't know how to fix. Hope it'll be useful.
