RES not found in BPL

I have a RES used in a BPL. When I try to create an APP which uses the
BPL as LIB (no packages) I get an error message saying DVRLOGO.RES not
found.

When I compile with packages no error.

When I add the dir where DVRLOGO.RES resides int library path, I get
this warning:

[Linker Warning] Duplicate resource:  Type  2 (BITMAP), ID
BMP_ILBLAUW; File D:\USER\WERK\DIVIREC\DVRECDLL\DVRLOGO.RES resource
kept; file D:\USER\WERK\DIVIREC\DVRECDLL\DVRLOGO.RES resource
discarded.

After somewhile I can remove the dir from the library path and then
everything works fine.

Why do I get the error in the first place?
And how can I use a RES in a BPL without the APP's needing it?

Thanks for any answers.
