I upgrade follow this [1] guide, using:

./configure --with-command-group=nagcmd
make all
make install

Previously I did not make changes in the users or groups. These are:

sparky:/usr/local/nagios/var/rw# id nagios
uid=1001(nagios) gid=1001(nagios) groups=1001(nagios),1002(nagcmd)
sparky:/usr/local/nagios/var/rw# id www-data
uid=33(www-data) gid=33(www-data) groups=33(www-data),1002(nagcmd)

In case it is of utility, after to run the 'configure', this is the
summary that I obtain:
