make install error with `install-exec-local-oct`

At the end of the installation step, I get this error:

make[2]: *** No rule to make target 'install-exec-local-oct', needed by 'install-exec-local'.  Stop.
...
make[1]: *** [Makefile:1453: install-am] Error 2
...
make: *** [Makefile:579: install-recursive] Error 1

can anybody confirm?
