Question

What is the cause of the "Missing Dependency: libpq.so.4" error and how do I fix it?

Asked by: HappyEngineer

Running "yum install subversion" gives me the dreaded "Missing Dependency: libpq.so.4" error. As soon as I saw it I wanted to slit my throat because the last time I encountered this I had to go through hell manually downloading rpms and forcing them to install (ignoring depencencies) until I got things working.

Can anyone explain what actually causes this error? Yum is a package manager which manages dependencies. Shouldn't it just install something if it's not installed?

This page tries to address the problem:
    http://linux.bgsnow.com/tag/libpq-so-4
however I can't uninstall postgres because I am using Postgres. But, I did try changing /etc/yum.repos.d/CentOS-Base.repo as it described, but it didn't seem to help.

My OS is CentOS-5.

Probably yum can't find libpq.so.4 under standard configured repositories. Try
yum whatprovides libpq.so.4
and probably you will get: No Matches found

If your repository is configured well, try to clean and reload the cache:
yum clean all

Also check what subversion requires:
yum deplist subversion
(under my CentOS 5 subversion doesn't require libpq.so)

The subversion from CentOS repository need "postgresql-libs" as dependency.
You can install the subversion for DAG repository, which newer version without postgresql-libs dependency.

# rpm -ivh http://dag.wieers.com/rpm/packages/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm

Did you try to setup to DAG repository by install
# rpm -ivh http://dag.wieers.com/rpm/packages/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

Then run
# yum install subversion
to see if this work

You are using a "rpmforge" repository. You should disable it and install CentoOS' subversion:

yum --disablerepo=rpmforge install subversion

Also check all files located under /etc/yum.repos.d; I should use only CentOS and eventually EPEL repositories:

[base]
name=CentOS-$releasever - Base
baseurl=http://mi.mirror.garr.it/mirrors/CentOS/$release/os/$arch/
enabled=1
gpgcheck=1
gpgkey=http://mi.mirror.garr.it/mirrors/CentOS/RPM-GPG-KEY-CentOS-5

[update]
name=CentOS-$releasever - Updates
baseurl=http://mi.mirror.garr.it/mirrors/CentOS/$release/updates/$arch/
enabled=1
gpgcheck=1
gpgkey=http://mi.mirror.garr.it/mirrors/CentOS/RPM-GPG-KEY-CentOS-5

[epel]
name=Extra Packages for Enterprise Linux 5 - $basearch
baseurl=http://download.fedoraproject.org/pub/epel/5/$basearch
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=http://www.mirrorservice.org/sites/download.fedora.redhat.com/pub/epel/RPM-GPG-KEY-EPEL

The way RedHat/CentOS pack subversion is tied to postresl. which is troublesome.

rpmforge is an alternative to provide newer version of rpm, in subversion's case, is much better than the one comes with CentOS.

Otherwise, download the subversion's source code and compole from scratch.
