Hacking page does not specify that binary needs envvars to be set
I've run a binary in separate terminal window only to see
./gimp-2.99: error while loading shared libraries: libgimpbase-3.0.so.0: cannot open shared object file: No such file or directory
error. It would be nice if the manual would state that all the envvars have to be set not only for build but also for being able to run the resulting binary.
