"Dying gasps received from client." with CVS 1.12.11

[gnu-cvs]

Hi,

Because of incompatible changes in GNU CVS 1.12.10 I need to make SmartCVS 
compatible again with GNU CVS >= 1.12.10.

For that, I've fetched the sources of GNU CVS 1.12.11 and built them on my 
local Knoppix system. Then I took the 'cvs' from the 'src' directory and 
uploaded it to our CVS/SSH server renaming it to 'cvs-1.12.11' and placing 
it in /usr/bin, where the normal GNU CVS 1.12.9's 'cvs' already lifes.

Instead of calling 'cvs server' as the SSH-command, I now call 'cvs-1.12.11 
server' instead. But for some mysterious reason, I get following error back:

  cvs-1.12.11 server: Dying gasps received from client.

I've googled a little bit, but could not find anything about that error. Is 
it possible, that uploading a binary is not enough for an upgrade?
