How can I tell whether I am running a module in development, or it has been installed?

Here is my challenge: I want to read a config file that might be different in development than in production. And they might be on the same machine. I use File::Sharedir for my read-only files, and that returns a different location in each case. But that location is not really ideal for config files. It is too obscure.

File::UserConfig does want I want, but returns the same directory during development as after installation.

How do others manage dev/prod config files without defining them absolutely in code?
