Package builder keeps sending fallout failure messages for the problems that have been long fixed

[Yuri]

As a maintainer of perftools, I am getting the messages like this:
[REL - 10i386-quarterly][devel/google-perftools] Failed for 
google-perftools-1.8.3 in build

The version 1.8.3 had problems at the time, but this has been fixed, and 
now it is a new version 2.X which works.
I am not sure, am I supposed to do something with this?

Why does the system now, in Feb 2014, still build packages with sources 
from Sep 2013?
