[DebianGIS-dev] Help with postgis and backport to lenny using pbuilder

Hi all,

I have just found pbuilder and I'm using it with the pkg-grass debian 
package definitions for geos-3.2.0 and postgis-1.5.1 building packages 
for lenny. This is all very cool and makes things soo much easier. I am 
also using some packages backports.org.

So, I have gotten things setup and have been able to build packages, but 
postgis and postgresql-8.3-postgis will not install giving the following 
error:

woodbri at mappy:/u/local/src$ sudo dpkg -i postgis_1.5.1-1_amd64.deb
[sudo] password for woodbri:
(Reading database ... 75044 files and directories currently installed.)
Preparing to replace postgis 1.5.1-1 (using postgis_1.5.1-1_amd64.deb) ...
Unpacking replacement postgis ...
dpkg: dependency problems prevent configuration of postgis:
  postgis depends on libpq5 (>= 8.4~0cvs20090328); however:
   Version of libpq5 on system is 8.3.9-0lenny1.
dpkg: error processing postgis (--install):
  dependency problems - leaving unconfigured
Processing triggers for man-db ...
Errors were encountered while processing:
  postgis

I have attached the postgis_1.5.1-1_amd64.build.gz from the pdebuild.

I think this might be because the control_lenny file has BOTH
    postgresql-server-dev-8.3, postgresql-server-dev-8.4
as Build-Depends for postgis.

Would this not then require BOTH

libpq5 8.4~0cvs20090328 from postgresql-8.4
libpq5 8.3.9-0lenny1    from postgresql-8.3

to be part of the dependencies, probably with the later one winning or 
whatever?

Any ideas how to fix this? Does the control file need to be split into 
two files one for postgresql-8.3 and one for postgresql-8.4?  would the 
rules file need to changes also or instead of the control file?

I've put a lot of time and effort into trying to resolve this, but I 
just don't know that much about building debian packages. Reall need to 
guidance and help on this one.

Best regards,
   -Steve
