Source RPM doesn't seem to install on CentOS without warnings

My experience with CentOS and RPM's is limited so I might be missing something obvious, but I can't seem to figure this out... I'm trying to install Sphinx into CentOS 6 in a Docker image using the instructions here: http://sphinxsearch.com/docs/current/installing-redhat.html (though, I'm trying to install from the source RPM instead of the binary) I run docker run -i -t centos:centos6 bash to get a CentOS image running and then here's what I get when trying to run the commands (slightly different than the instructions to give more information and skip prompts): [root@db60006ae258 /]# yum -y install postgresql-libs unixODBC Loaded plugins: fastestmirror Setting up Install Process base | 3.7 kB 00:00 base/primary_db | 4.6 MB 00:37 extras | 3.4 kB 00:00 extras/primary_db | 34 kB 00:00 updates | 3.4 kB 00:00 updates/primary_db | 3.3 MB 00:08 Resolving Dependencies --> Running transaction check ---> Package postgresql-libs.x86_64 0:8.4.20-4.el6_7 will be installed ---> Package unixODBC.x86_64 0:2.2.14-14.el6 will be installed --> Processing Dependency: libltdl.so.7()(64bit) for package: unixODBC-2.2.14-14.el6.x86_64 --> Running transaction check ---> Package libtool-ltdl.x86_64 0:2.2.6-15.5.el6 will be installed --> Finished Dependency Resolution Dependencies Resolved ========================================================================================================================================== Package Arch Version Repository Size ========================================================================================================================================== Installing: postgresql-libs x86_64 8.4.20-4.el6_7 updates 202 k unixODBC x86_64 2.2.14-14.el6 base 378 k Installing for dependencies: libtool-ltdl x86_64 2.2.6-15.5.el6 base 44 k Transaction Summary ========================================================================================================================================== Install 3 Package(s) Total download size: 624 k Installed size: 1.8 M Downloading Packages: (1/3): libtool-ltdl-2.2.6-15.5.el6.x86_64.rpm | 44 kB 00:00 (2/3): postgresql-libs-8.4.20-4.el6_7.x86_64.rpm | 202 kB 00:00 (3/3): unixODBC-2.2.14-14.el6.x86_64.rpm | 378 kB 00:01 ------------------------------------------------------------------------------------------------------------------------------------------ Total 234 kB/s | 624 kB 00:02 warning: rpmts_HdrFromFdno: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 Importing GPG key 0xC105B9DE: Userid : CentOS-6 Key (CentOS 6 Official Signing Key) Package: centos-release-6-7.el6.centos.12.3.x86_64 (installed) From : /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Installing : libtool-ltdl-2.2.6-15.5.el6.x86_64 1/3 Installing : unixODBC-2.2.14-14.el6.x86_64 2/3 Installing : postgresql-libs-8.4.20-4.el6_7.x86_64 3/3 Verifying : postgresql-libs-8.4.20-4.el6_7.x86_64 1/3 Verifying : unixODBC-2.2.14-14.el6.x86_64 2/3 Verifying : libtool-ltdl-2.2.6-15.5.el6.x86_64 3/3 Installed: postgresql-libs.x86_64 0:8.4.20-4.el6_7 unixODBC.x86_64 0:2.2.14-14.el6 Dependency Installed: libtool-ltdl.x86_64 0:2.2.6-15.5.el6 Complete!
