cups web interface broken on 3.99.21

[mrk%coris.org.uk@localhost]

Hi,

I jsut installed cups from a current pkgsrc on 3.99.21 (i386).

The problem i have is that when i go to localhost:631/admin all i get is a 
blank page.

I can get to localhost:631 but all links (that dont go to an external site) 
show a blank page.

I tried using kde to set up my printer but it doesnt show any printers in 
its list.

Any one know whats going on?

I have cupsd=yes and slpd=yes in my rc.conf.

Thankss in advance

Mark
