A bug in Espeak 1.30 and questions on updating to 1.31

[Hermann]

Hi,
since upgrading Espeak to 1.30, I get some strange behavior of Espeak: 
Obviously without any reason, speech suddenly changes to English. I use 
the German language as default and set up SD to use German as default 
language. Before 1.30 it was no problem.
I cannot reproduce this behavior, it suddenly shows up while reading 
text, and scrolling around with the error keys brings German back.
So I decided to upgrade to Espeak 1.31, but unfortunately there's no 
actual debian package til today.
I downloaded the source package and performed the makefile in the src 
subdirectory as recommended in the readme file.
I get a bunch of error messages regarding the speak.cpp file and the 
installation failed. I also did
apt-get build-dep espeak
What can i do? Will there be a debian package in the near future?
