Hmmm...
I tried that and setup didn't show such a package! So, I tried a different
mirror and found it elsewhere. It's downloading now.
However, this brings up a VERY key point, I think: How was it possible for
me to do an installation like this and NOT get readline? And not know
about it at the time? I mean, shouldn't the dependencies mechanisms caught
this? If I download an incomplete set of materials from some mirror
somewhere, how do I catch this other than just trying to fix whatever
problems crop up?
This has me thinking that over the years I may have had this happen before
to me and my coleagues as, for example, quite notably sshd wouldn't work
and I never had the time to troubleshoot it...
For that matter, can I download an ISO image from somewhere and thus
guarantee I get the whole thing? Buy a DVD?
Thanks,
Richard
