However FFmpeg fails to install on current Debian because it tries to
create the installation directory with 'install -d'. If you run 'make
install' as non-root then 'install -d /usr/local/bin' fails because you
cannot change the permissions of that directory. If you run 'make
install' as root then the installation itself will work but it will
break the permissions of /usr/local/bin so that it's no longer writable
by group staff.

Reportedly some older versions of the install binary behave differently
and do not set permissions of already existing directories. Autotools
uses 'mkdir -p' to create directories which works fine.
