This is a variant of bullet built with a configure flag for double
precision arithmetics required by openmw 0.47.

* gnu/packages/game-development.scm (bullet-double-precision): New
  variable.

I'm curious, did you try making this change in the 'bullet' package
itself, and then rebuilding the packages that depend on it? It would be
