Mercurial is a DVCS that we use. Not sure why rosmake would issue those warnings -- my colleagues might be able to 
provide more information on that.

As always, in order to help you better, it's good to provide some information regarding your operating system, compiler, 
versions, etc.

An internal compiler error is a serious one, and I cannot think of a reason why compiling dynamic_reconfigure would give 
you that.

At this point, my recommendation for path of least pain is to install unstable or diamondback, and see if that works out.
