libvorbis - replace

[Riccardo Mottola <riccardo.mottola%libero.it@localhost>]

Hi,

I'm using pkg rolling replace the first time (thanks Greg!).  Seems a 
fine tool I wonder how I could have lived without it...

I get this error:

===> Replacing for libvorbis-1.3.4
WARNING: experimental target - DATA LOSS MAY OCCUR.

Hints?
