Hi Andrew: I have read this detailed analysis and I understand a bit better how to handle rpms.
However I just spent some time reading the upgrade manual provided by Ensim (probably should have done that first before upgrading). In there thay talk about some of the dependency rpm errors that may be encountered and how to handle them for their software upgrade to go smoothly. I saw the one with the readline problem, and their solution is to load the versions of those that will work with the later version of readline their install script will use in the /tmp/extrarpms directory and their upgrade script will take care of the rest. There are other scenarios they talk about which I will probably encounter and how to deal with them. I just have one question from option 4). I can't see how to get the current version of say Mqsql, dump for the version of readline I am installing. You state recompiling. Their install script will take care of everything so long as I load the version it wants for readline they want installed. So how do I find this out ?
