Rbbg for 2.15.2

Dear R Users,

Anyone know of a version of Rbbg compiled for R 2.15.2 . The current 
version does not appear to work with 2.15.2

 > install.packages("Rbbg", repos = "http://r.findata.org")
Installing package(s) into ?C:/Users/t_uzu_000/Documents/R/win-library/2.15?
(as ?lib? is unspecified)
Warning: unable to access index for repository 
http://r.findata.org/src/contrib
Warning message:
package ?Rbbg? is not available (for R version 2.15.2)

Thanks in advance,
Tolga
