Description of problem:
The version of tmux in EPEL depends on a version of libevent that is not available on CentOS 4 / RHEL 4
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. CentOS 5.4 - x86_64
2. Enable EPEL
3. yum install tmux
Setting up Install Process
--> Running transaction check
---> Package tmux.x86_64 0:1.4-3.el5.1 set to be updated
--> Processing Dependency: libevent-1.4.so.2()(64bit) for package: tmux
--> Finished Dependency Resolution
tmux-1.4-3.el5.1.x86_64 from epel has depsolving problems
--> Missing Dependency: libevent-1.4.so.2()(64bit) is needed by package tmux-1.4-3.el5.1.x86_64 (epel)
Error: Missing Dependency: libevent-1.4.so.2()(64bit) is needed by package tmux-1.4-3.el5.1.x86_64 (epel)
# Note - libevent 1.1 is installed, from base.
libevent 1.4 and tmux1.4 would be installed
I see now that the libevent-1.4 is available in 5.5 and 5.6 os repos.
For others with this problem, you probably have a bad repo file, mine, from RightScale, was hard coded to the 5.4 repo.
