I'm trying to do an installp of rpm.rte but I'm getting an error on a missing requisite of bos.rte.libc. I can find the directory with rpm.rte on ftp.software.ibm.com and was expecting to find bos.rte.libc in there as well - I mean if there was a dependency shouldn't they both be available for download?? What's up here? Ron I found the below about 5 minutes after posting, I think that answers my question: To get to libc version 5.1.0.0 you would have to update your OS to AIX 5.1. There should be an old version of rpm for AIX on ftp://ftp.software.ibm.com/aix/freeSoftware/aixtoolbox/INSTALLP/ppc/ Try the older ones and also you might check the Bull site: http://www.bullfreeware.com/ In case anyone finds this via a google, I went to the above ftp site and downloaded the .rte version ending in .20 to my 4.x.x host and that worked fine, rpm -i was up after the install.
