Yes, it's probably just a pining problem. You can also see if the
package is available with its pin number with: apt-cache policy libpq5

Does this mean that I need to pin libpq5 that is in backports.org or
am I still missing something else?

Hi Stephen,
Just a quick thing you could try: "apt-get install -f" , this should
install the missing dependency and continue the postgis package
installation normally. Be sure you have lenny-backports in you
sources.list because the libpq5 version 8.4 is there. Note that dpkg
will never download and install missing dependencies, it's not its
job. It's the apt-get job. That's why you have to call apt-get to fix
things and continue what dpkg started before. You can also take a
look at the "gdebi" utility. It's a tool to install a .deb file and
it *should* (never used it much) call apt-get itself to solve missing
dependencies.

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:

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.
That is ok, the package is made to build the postgis extension for
both versions.
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?
No. libpq5 is the library that allows user programs to communicate
with a postgresql server. The version of libpq5 >=8.4 is compatible
to communicate with servers from PostgreSQL 8.2 or later. So it's all
right that the postgis package has libpq5 >=8.4.x as dependency.
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?
As I said, the control and rule files are ok and build the extension
for postgresql 8.3 and 8.4.
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
