hylafax 4.1.3 port wants to install the httpd docs in /var/httpd
rather than /usr/local/www/data, which is the FreeBSD standard
location for such (or perhaps /usr/local/share/doc).
it also doesn't seem to actually install said docs.
dunno what's going on. why does it ask where to put it if there's
nothing put there?
Committed an appropriate fix.
