xmvlog: *E,MULPAK

I am trying to simulate a design with multiple packages .  I use the "-makelib/-endlib" options in xrun to specify all of the files .  However, I have run into a problem with packages.  In this case, I have 2  directories that both have a same file name  in their respective directories. 

-makelib bt_core_r_rtl_lib_fullchip

    btrip_bt_rfif_shrf.sv
    bt_shrf_bus_pkg.sv

-endlib

---------

-makelib bt_core_r_f2rf_lib

    bt_shrf_bus_pkg.sv

-endlib

----------

When I try this, I get an error *E,MULTPK...Multiple (2) packages were found in searched libraries:

xmvlog: *E,MULPAK (btrip_bt_rfif_shrf.sv,50|23): Multiple (2) packages named "bt_shrf_bus_pkg" were found in the searched libraries:

-> found verilog_package bt_core_r_f2rf_lib.bt_shrf_bus_pkg:sv (VST)

-> found verilog_package bt_core_r_rtl_lib_fullchip.bt_shrf_bus_pkg:sv (VST).
import bt_shrf_bus_pkg::*;

How can i solve it ?
