We're unable to upgrade our environment beyond CentOS 5.10. This is a webserver that has certain reliances to the specific version of the OS, long story short.
I was asked to install a plugin for Redmine that requires at least ruby 1.8.7 so I cloned our VM as a new machine to test functional checkout. The problem is, the existing installation of Ruby was also installed ad hoc (not from any repo or yum methods) and it's currently at 1.8.5. The 1.8.7 version I tried to install gives me the following:
# rpm -Uvf ruby-22.214.171.1244-2.el6.x86_64.rpm warning: ruby-126.96.36.1994-2.el6.x86_64.rpm: Header V3 RSA/SHA1 signature: NOKEY, key ID c105b9de error: Failed dependencies: rpmlib(FileDigests) <= 4.6.0-1 is needed by ruby-188.8.131.524-2.el6.x86_64 ruby-libs = 184.108.40.2064-2.el6 is needed by ruby-220.127.116.114-2.el6.x86_64 rpmlib(PayloadIsXz) <= 5.2-1 is needed by ruby-18.104.22.1684-2.el6.x86_64 ruby = 1.8.5-31.el5_9 is needed by (installed) ruby-irb-1.8.5-31.el5_9.x86_64 ruby = 1.8.5-31.el5_9 is needed by (installed) ruby-rdoc-1.8.5-31.el5_9.x86_64 ruby = 1.8.5-31.el5_9 is needed by (installed) ruby-ri-1.8.5-31.el5_9.x86_64
It appears as though this particular version was intended for CentOS 6 and, as I've known from previous experience, dependency hell is upon me. So, the question becomes, has anyone successfully upgraded ruby without tinkering with the OS version upgrade and, if so, might you have a HOWTO that prevents dependency hell? This, short of installing from source, is headed in the wrong direction real quick so I'm trying to stick with the RPM method. But, obviously, I'll listen to anything at this point.
