Yum does not resolve dependencies after a rpm -ivh installation - dependency-management

Question

I use AWS EC2 instances.
I wanted to setup a package versioned at 5.4.0 but the latest that yum search all --enablerepo epel offered was 5.0.0.
I hence did wget and configure && make && make install on v5.4.0 which was available on the web.
Since we do a lot of instance ups and downs, this solution was too time consuming (the compile time) to become a viable solution on deployment.
I then built an RPM from the tar.bz2 versioned at 5.4.0. To ensure libraries and dependencies are no different between the environments, I ran rpmbuild on the same instance as our deployment AMI.
After having had built and deployed the RPM on a test server, I tried installing gearmand to the following result-
[ec2-user#ip-10-0-0-62 ~]$ sudo yum install --enablerepo=epel gearmand
Loaded plugins: priorities, update-motd, upgrade-helper
565 packages excluded due to repository priority protections

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
This makes me suspect that the RPM installation is in some sense 'freezing and blocking' the libraries it depends upon. I feel this way, because while building the RPM, the package expected higher library versions than those available on amazon or epel repos. Some examples-
+-------------+-------------------+----------------+
| name | amazon version | library wants |
+-------------+-------------------+----------------+
| glibc | 2.12 | 2.16 |
| perl | 5.10 | 5.18 |
| python | 2.6.9 | 2.7 |
+-------------+-------------------+----------------+
Am I doing something wrong here, do I need to change something in the source/spec before building the RPM? Because this looks like just the tip of the iceberg.

Answer 1

Change rpm-spec file where you can edit the required dependencies version
