Yum does not resolve dependencies after a rpm -ivh installation

Question

1. I use AWS EC2 instances.
2. 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.
3. 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.

4. 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.
5. 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

 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
