erratic_player has a file named erratic_player in it. Thus, roslaunch can't distinguish whether you mean the file or a package name. roslaunch makes no assumptions about the file extensions of what it is run on.

BTW: our general convention is to compile executables into a 'bin' subdirectory, which would circumvent this issue.

Starting this roslaunch script works fine:

roslaunch erratic_player erratic_server.launch

...unless I'm connected to the erratic_player package directory.  This
is a bit surprising; I'd expect it to work from anywhere.  The error:
