Debian sid install

[Geordie]

Hi
I would like to install the Kolab server on a Debian sid system via apt-get. I 
am getting dependency problems when trying to install kolab-cyrus-common. It 
says I need libzephyr3 and this program is not available in the sid packages.
Is there a current work around for this?
And if possible I would like to do this via apt-get.
Any suggestions would be appreciated.
Thanks
Geordie
