Somehow I managed to break apache. The command apachectl restart gives the error:
/usr/sbin/apachectl restart: httpd not running, trying to start
Syntax error on line 128 of /etc/httpd/httpd.conf:
Cannot load /usr/local/libexec/httpd/libphp4.so into server: (reason unknown)
/usr/sbin/apachectl restart: httpd could not be started
I checked to see that libphp4.so was indeed in /usr/local/libexex/httpd and it is.
The possibility existis that I inadvertently deleted something critical from /usr/local.
Any ideas?
