proj1 depends on

Answer 1

Create a (local) repository and use yum to have it resolve the dependencies for you.

The CentOS wiki has a nice page providing a how-to on this. CentOS wiki HowTos/CreateLocalRepos.

Summarized and further minimized (not ideal, but quickest):

1. Create a directory for you local repository, e.g. /home/user/repo.
2. Move the RPMs into that directory.

3. Fix some ownership and filesystem permissions:

   # chown -R root.root /home/user/repo
   

4. Install the createrepo package if not installed yet, and run

   # createrepo /home/user/repo
   # chmod -R o-w+r /home/user/repo
   

5. Create a repository configuration file, e.g. /etc/yum.repos.d/myrepo.repo containing

   [local]
   name=My Awesome Repo
   baseurl=file:///home/user/repo
   enabled=1
   gpgcheck=0
   

6. Install your package using

   # yum install packagename
