The error messages seems to have been caused blank lines in
/etc/conf.d/apache2  Once I deleted those lines: no startup or configtest
errors...
BUT apache still does not load mod_access, mod_info and mod_status for some
reason. It used to do this before I updated PHP.

I guess that must have to do with the APACHE2_OPTS
OK that's fixed also now (gremlins)
I had changed the line from:
APACHE2_OPTS="-D DEFAULT_VHOST -D SSL_DEFAULT_VHOST -D CGI -D PHP5CGI -D
PHP4 -D SSL -D PYTHON -D PERL -D INFO"
to
APACHE2_OPTS="-D DEFAULT_VHOST -D SSL_DEFAULT_VHOST -D CGI -D PHP5 -D SSL -D
PYTHON -D PERL -D INFO"
by deleting out the php4 stuff and that seems to be what broke it (it's not
like I changed that part of the line and PERL was loading).
To fix it I cut -D INFO from the end and put it just before -D PERL and now
it works, like I say: gremlins. Who knows? And now I've put it back where it
was and it also works!
 I guess why ask why. Happy that it is working again.
