Translation of 2 strings on Activity

Hi all

Using buddypress 1.9
I′m having trouble trying to translate 2 strings on Activity′s:
================================
%1$s wrote a new post, %2$s
and
%s posted a new activity comment
====================================

I′ve found those strings on buddypress.pot and so on my native language po and mo:
======================================
#: bp-blogs/bp-blogs-functions.php:333
msgid “%1$s wrote a new post, %2$s”
msgstr “%1$s escreveu um novo post, %2$s”

#: bp-blogs/bp-blogs-functions.php:442
msgid “%1$s commented on the post, %2$s”
msgstr “%1$s comentou o post, %2$s”

#: bp-blogs/bp-blogs-functions.php:331
msgid “%1$s wrote a new post, %2$s, on the site %3$s”
msgstr “%1$s escreveu um novo post, %2$s, no site %3$s”
=========================================================
BUT they are not on Mesocolumn′s po

As i did not find any corresponding Mesocolumn template I′m pretty lost ??

Any clue on how get those strings translated?

Thank you

BTW> as soon as i′ve finished the translation I′ll be glad on sending the files to You Richie.
