I believe that portal pages can only be deleted when two conditions are met:
1. There are no portlets on the page (i.e. you have removed all the portlets)
2. The page is the last page for the portal
Yes, it's a pain, but that's the way it is at present. If you have 3 pages, and you want to remove page 2, you have to remove all the portlets from page 3, delete page 3, remove all the portlets from page 2, delete page 2, then put page 3 back (as page 2).
It is reported as a bug: https://openacs.org/bugtracker/openacs/com/dotlrn/bug?bug%5fnumber=476
Oh, the same procedure applies to reordering the pages :)
