There was some discussion that Abebereira was the same as Berbera, or Bebera Preta. You might have better luck finding it under that name. I bought a Berbera tree last year from Will's Figs.
There are “5 fresh Abebereira tree Cuttings” for sale now on eBay but they are a little pricy. The other names and info on it are posted there as well: “Abebereira originates from Madeira Island, Portugal. The mother tree in the U.S. resides in Point Loma , CA and has been grown since the 1950s by an older Portuguese lady. A large purple/black fig that produces two crops per year in warmer climates. During peak season, each fig can weigh over 100 grams. This fig is also known as Bebereira & Bêbera Preta in Madeira Island, Portugal.”
