During the ./configure build stage, error './configure.gnu: line 1: -e: command not found' can occur. Problem: the -e flag with echo is not portable. While some shells support it (e.g., Bash), others (e.g., POSIX /bin/sh on some systems) do not. Solution: replacing echo -e with printf, since printf is POSIX-compliant and works consistently across different shells.
