If you quoted correctly, then the IDE already knows the package,
because it knows that an unit with the name <package_name> is in the
package named <package_name>.

Check if you can rebuild the IDE without this package.
If that succeeds then either the package has a bug or you have some old
files on your disk, which need to be deleted before building.
Have you tried a clean build? Tools / Configure Build Lazarus / Clean
