installing opengroupware.org on unstable

[Pim Bliek <bliekp@pingwings.nl>]

Hi,

I am having troubles installing OpenGroupWare.org on my Sid box:

fourtytwo:~# apt-get install opengroupware.org
Reading Package Lists... Done
Building Dependency Tree... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
 
Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:
 
The following packages have unmet dependencies:
  opengroupware.org: Depends: opengroupware.org-gstep-db but it is not
going to be installed
                     Depends: opengroupware.org-gstep-db-postgresql72
but it is not going to be in stalled
                     Depends: opengroupware.org-database but it is not
going to be installed
                     Depends: libpgsql2 but it is not installable
E: Broken packages
fourtytwo:~# apt-get install libpgsql2
Reading Package Lists... Done
Building Dependency Tree... Done
Package libpgsql2 has no available version, but exists in the database.
This typically means that the package was mentioned in a dependency and
never uploaded, has been obsoleted or is not available with the contents
of sources.list
However the following packages replace it:
  libpqpp libpq3 libpgeasy-dev
E: Package libpgsql2 has no installation candidate
fourtytwo:~# apt-get install libpqpp libpq3 libpgeasy-dev
Reading Package Lists... Done
Building Dependency Tree... Done
libpqpp is already the newest version.
libpq3 is already the newest version.
libpgeasy-dev is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Anyone any clues on how to solve this?
