It is expected that large Rakefiles will require some effort in
getting the full graph correct. If you push a branch to github which
removes the chdirs I will take a look. Also I assume you've changed
this stuff:
Dir['*.cpp'].each do |file|
compile_cxx ...
end
That's clearly not going to get parallelized since there are no Rake
tasks there.

I tracked this down to graphviz not understanding slashes and dots in
node names (depgraph.rake was, after all, a toy I quickly wrote then
threw away). I cherry-picked the deleted file back into master and
committed a fix.
