This issue continues for version 7.14.0.

I found a work-around a while back and posted it to the Gembud list, see that post for the details.

Here are the steps to get past this:

1. Install as one normally would, pausing after the make all >& make.out step.
2. Edit ~/NAWIPS/config/Makeinc.linux64_gfortran_ubuntu and add LIBBZ2 = $(OS_LIB)/libbz2.a -ldl at the bottom.
3. Re-run make all >& make.out
4. Continue the install as one normally would.

I've confirmed this works on Ubuntu 18.04 LTS and 20.04 LTS.
