Why do recompile attempts fail with Makefile?

When attempting to recompile an app that is currently running on Redhat 7.9 to new platform running AlmaLinux 8 the following error occurs:

/usr/bin/ld: cannot find -lgfortrancollect2: error: ld returned 1 exit statusmake: [pest.mak:307: pest] Error 1

But Fortran, GCC, and G++ are installed as shown here:

I appreciate any insights you folks can offer.
