Yes, it's repeatable. As I mentioned, this is an ubuntu, virtual server (user mode linux). I'm thinking this may have to do with the "exoticness" of my system. So, I will repeat this question at the linode forum (linode is my virtual hoster, and the forum there has a lot of knowledgable users), and report back here if I learn anything useful. Worse case, I'm stuck with ghc 6.4 on my server, which I can (grouchily) live with. If anyone out there has installed ghc 6.6 on any kind of virtual linux, or better yet user mode linux (as opposed to XEN, or virtuozzo, or the other flavors), would be useful to know that as well. Thanks for pointing me in a likely right direction. http://www.linode.com/forums/viewtopic.php?p=11420#11420 -- View this message in context: http://www.nabble.com/trouble-installing-ghc-6.6%3A-xargs%3A--usr-bin-ar%3A-...
