I don't have that attitude and I'm sorry if you encountered it (it's true the Lisp community could be friendlier, warmer to newcomers). However, what can a I (or any other Lisp programmer for that matter) do about the steep learning cure you mention? You have to try for yourself to learn the language, noone's going to do it for you.
Create a simple working installer for the major OS's that includes a useful IDE, Database connectivity to least one major database and a fully functional web server. Once this is working get some people to write a standard library for date / time functions, file IO, formatting output etc.
Never underestimate how difficult it is for a new user to setup a working environment.
It's Aquamacs combined with SBCL, some documentation, and some should-be-standard CL libraries. Double click and it immediately takes you into a REPL. Aquamacs recognizes most of the usual Mac key bindings, making the Emacs curve not quite so steep.
Lispbox is a good idea. Target Windows if you can. Setting up Clojure with Emacs on Windows involved a lot of steps and arcane stuff, but now there's a Clojure Box which makes things a lot more pleasant.
I've tried SBCL with the Eclipse plugin and it's been a huge PITA. IIRC, I couldn't get libraries to install when I finally gave up. It may have improved since, but I'm not sure. Of course the fact that many cool-sounding CL libraries had defunct websites and inaccessible CVS repos didn't exactly encourage me...

In the comments there are instructions to get ASDF working, that I haven't tried yet.
I've tried to avoid Emacs, but it seems impossible. Lisp in a Box has a lot of problems, ABLE has still too many bugs and Corman lacks GUI programming without which I can't justify the price. CUSP also has too many bugs. So I'm surrendering and looking at Emacs.
