[ros-release] collada error during apt-get dist-upgrade

It looks like the new collada packages that were pulled in recently are 
causing upgrade problems.

I did an apt-get dist-upgrade on my system today, and it looks like 
there's a collision between collada-dom2.4-sp-dev and 
collada-dom2.4-dp-dev, and apt wants to install both at the same time:

Thoughts? Known workarounds?

Is there a known reason why apt would want to install the sp and dp 
versions at the same time? Up until now I think I've only had the dp 
version installed.

If the sp and dp versions aren't supposed to be installed at the same 
time, can the maintainer please add a Conflicts: to the package header?
