Since it sounds like you are using Quartus to run Modelsim, use Quartus to change the library those two packages are compiled into, eg., right click on the files, and set the library to rtl_work (I think that is how you do it).

Leads to quartus compilation error:

I'm trying the alternative method.
PS: Properties->library-> rtl_work, if i return to erase rtl_work from the Properties->library-> rtl_work, quartus compilates ok.
