Regardless the DESTDIRS Unix mystery (!?) BIN_DESTDIR and LISP_DESTDIR
are set correctly. But looking at you original error apparently Emacs
is convinced to start from '/usr/bin/' and not
'/home/alex/src/emacs/install/bin/'.
This '/usr/bin/' should be the value of `invocation-directory' while
executing pdumper.c:5312. Is this value wrong or we are missing
something else?
