I don't see a problem here (but may be I just don't know enough about how this new install feature works).

Each package is responsible to find resources located somewhere "inside" the own package.
Therefore it must use a reasonable install destination for all those resources so that they are still found.

I.e. the package "rosgui" uses an image which is stored inside the package in the relative path "icons/ros_org_vertical.png".
The "basedir" for loading the image is actually the path of the package as returned by ROS.
If ROS returns "/path/to/packageN/" as the package path the image must be installed to "/path/to/packageN/icons/ros_org_vertical.png".
