No, see #417545.

It's approximating

( libapache2-mod-perl2 | 
  speedy-cgi-perl | 
  ( libapache2-mod-fcgid,   libcgi-fast-perl) |
  ( libapache2-mod-fastcgi, libcgi-fast-perl)
)

because both libapache2-mod-fcgid and libapache2-mod-fastcgi need
libcgi-fast-perl but the others don't.

Like the above: libapache2-mod-perl2 needs libapache-dbi-perl, the others don't,
so it's actually

( ( libapache2-mod-perl2, libapache-dbi-perl ) | 
  speedy-cgi-perl | 
  ( libapache2-mod-fcgid,   libcgi-fast-perl) |
  ( libapache2-mod-fastcgi, libcgi-fast-perl)
)

Suggestions for better expressing the above in the dpkg dependency syntax
are welcome. It would also be nice to take other web servers than apache2
into account, see #503454 and #486633.

I've been thinking about empty dependency packages like rt3.8-db-*
for this, but that seems bloatish at least as long as we don't have
any framework for actually setting up the web service. (Sean Finney
was working on a webapps-common draft at some point, but I believe
that's stalled)

Hope this explains,
