I think it is good to sometime build apps without using tools like yum and aptitude, from time to time.
It's good to keep our skills current on how to actually troubleshoot library problems that arise; and to just depend on tools like yum or aptitude hides what is going on.
... kind of like when people use a GUI to do things they can do in the shell easier; they start to lose their core / basic understanding of the shell and the filesystem, etc.

SYNOPSIS
yum-versionlock [ package-name [ package-name]] ...
DESCRIPTION
yum-versionlock(1) is a Yum plugin that takes a set of name/versions for packages and excludes all other versions of those packages
(including optionally following obsoletes). This allows you to protect packages from being updated by newer versions.
The plugin provides a command "versionlock" which allows you to view and edit the list of locked packages easily.
yum versionlock add <package-wildcard>...
Add a versionlock for all of the packages in the rpmdb matching the given wildcards. yum versionlock exclude <package-wildcard>...
Add a exclude (within versionlock) for the latest versions of the packages in the available repos. matching the given wildcards. yum ver-
sionlock list
List the current versionlock entries. yum versionlock delete <entry-wildcard>...
Remove any matching versionlock entries. yum versionlock clear
Remove all versionlock entries.
FILES
/etc/yum/pluginconf.d/versionlock.conf
The system wide configuration file. See yum-versionlock.conf(5) for more information.
/etc/yum/pluginconf.d/versionlock.list
The default place to put package version lock information (one package and version per. line). The file takes entries in the follow-
ing format EPOCH:NAME-VERSION-RELEASE.ARCH See rpm(8) for more information on custom query formats. If the package does not have an
EPOCH the number will default to 0.
