There should be one - perhaps it's named something else or resides deep
down in a subdirectory?

Evolution's packaging probably uses a patch system. Run "what-patch"
(this tool is present in the ubuntu-dev-tools package) to see what patch
system is used - if it says something like "quilt", "dpatch", etc, you
need to learn how to use this patch system.
Also, this is an upstream bug - it might make more sense to work
directly with upstream to try to provide a solution, and then downstream
it to Ubuntu?
