Fixing the www/wml port

[Rodrigo (ros)]

Hi fellow porters,

After some changes I finally obtain a working patch for the
www/wml port. This version is now functional with the 5.8.8
perl version.

The new port is available for test here :

If you are a wml user, please feel free to test this version and give me 
some feedback
before I submit it for change.

Thanks
- Rodrigo
