dwww can't read some files

[prad <prad@towardsfreedom.com>]

once in a while i get
dwww will not allow you to read the file

for instance, when i look for clusterdb by searching for postgresql and
choosing the clusterdb link the error message is

Access denied
dwww will not allow you to read the file
/usr/share/postgresql/8.4/man/man1/clusterdb.1.gz 

the permissions are rw-r-r

yet these items all show up on a straight man:
man clusterdb

and will work even with dwww if i go a circuitous route:
click Manual pages
click C
click clusterdb

so it seems that there are 2 sets of man pages because the latter reads
fine from:
http://localhost/cgi-bin/dwww/usr/share/man/man1/clusterdb.1.gz?type=man
which is a softlink to
/etc/alternatives/clusterdb.1.gz

is there a way i can get dwww to work from the postgresql directory?
