¿Cómo comprobar si los permisos de /usr/local, /usr/local/bin, /usr/share/man/man1 han sido alterados, y cómo restaurarlos?

Intenté instalar tree de la fuente. Ejecutando make install la primera vez, obtuve esta salida:

...$ make install
install -d /usr/local/bin
install: chmod 755 /usr/local/bin: Operation not permitted
install -d /usr/share/man/man1
install: chmod 755 /usr/share/man/man1: Read-only file system
if [ -e tree ]; then \
        install tree /usr/local/bin/tree; \
    fi
install: /usr/local/bin/tree: Permission denied
make: *** [install] Error 71

Dado que la respuesta menciona el uso de sudo , corrí sudo make install que funcionaba para lo que se refiere a mover el tree binario a /usr/local/bin pero no por lo que se refiere a añadir el man páginas:

install -d /usr/local/bin
install -d /usr/share/man/man1
install: chmod 755 /usr/share/man/man1: Read-only file system
if [ -e tree ]; then \
        install tree /usr/local/bin/tree; \
    fi
install doc/tree.1 /usr/share/man/man1/tree.1
install: /usr/share/man/man1/tree.1: Read-only file system
make: *** [install] Error 71

Sin embargo, ahora me temo que he cambiado los permisos de mis carpetas del sistema. Al menos parece ser el caso de /usr/local/bin (mira la hora y la fecha de . ):

...$ ls -alt /usr/local/bin
total 1912
-rwxr-xr-x   1 root           wheel  109008 Dec  8 15:11 tree
drwxr-xr-x  44 root           wheel    1408 Dec  8 15:11 .
drwxr-xr-x  23 root           wheel     736 Sep 26 10:12 ..
.
.

¿Cómo puedo comprobar si los permisos de mis carpetas del sistema han sido alterados y cómo puedo restaurarlos? ¿Tengo que comprobar sólo /usr/local/bin y /usr/share/man/man1 ¿o debo comprobar también otras carpetas? Aquí está el Makefile por si quieres mirarlo:
