Ok.

But this line means that you have changed back to the case where all libraries should be compiled into the work library.

but we are stuck at modelsim:

Read the error message - its telling you that its looking for library ieee_proposed. Doesn't that make you think:

oh, i thought i edited that file and changed those lines to use work.fixed_pkg.all;

Then you would edit the file, re-run the example and not have an issue. Try that, and let me know how it goes.

Cheers,
