Dependancies within multi-binary packages

[Nikolai Lusan <nikolai.lusan@hitwise.com>]

Hi,

I am building some multi-binary packages. The packages contain libraries
that other packages in the same build will depend on. Because the
packages I am building potentially conflict with some already in the
repository I have renamed them all with an extenstion denoting their
purpose. In the control file I am setting the "Conflicts" and "Provides"
to turn the libraries into "virtual packages" and  using
"${shlibs:Depends}" to define lib requirements. When I install my custom
libs dpkg does not seem to recognise the "Provides" section and tells me
that required libs are not installed -
Example:

>From control file:

   Package: libpq4-hw
   Architecture: any
   Section: hw/libs
   Depends: ${shlibs:Depends}
   Conflicts: libpq4
   Provides: libpq4
   Description: PostgreSQL C client library

   Package: postgresql-client-8.0-hw
   Architecture: any
   Section: misc 
   Depends: ${shlibs:Depends}, postgresql-client-common
   Conflicts: postgresql (<< 7.5), postgresql-client-8.0
   Provides: postgresql-client-8.0
   Description: front-end programs for PostgreSQL 8.0


Once I install the libpq4-hw package dpkg will still complain:

user@host # dpkg -i postgresql-client-8.0-hw_8.0.7-1_i386.deb 
Selecting previously deselected package postgresql-client-8.0-hw.
(Reading database ... 22134 files and directories currently installed.)
Unpacking postgresql-client-8.0-hw (from
postgresql-client-8.0-hw_8.0.7-1_i386.deb) ...
dpkg: dependency problems prevent configuration of
postgresql-client-8.0-hw:
 postgresql-client-8.0-hw depends on libpq4 (>= 8.0.4); however:
  Package libpq4 is not installed.
dpkg: error processing postgresql-client-8.0-hw (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 postgresql-client-8.0-hw



The dependencies for the client package look like:

 Package: postgresql-client-8.0-hw
 Version: 8.0.7-1
 Section: misc
 Priority: optional
 Architecture: i386
 Depends: libc6 (>= 2.3.2.ds1-21), libpq4 (>= 8.0.4), libreadline5,
zlib1g (>= 1:1.2.1), postgresql-client-common
 Conflicts: postgresql (<< 7.5), postgresql-client-8.0
 Provides: postgresql-client-8.0


Does anyone know how I can fix this one?
