The options for step 1 are a bit sparsely explained. ANY advice on the options for extconf.rb would be greatly appreciated. You guys are right! It is a bad install. I didn't know Rails shipped with its own mysql drivers. That is an interesting thing to know though. I took a look at the mkmf log file and sure enough, it has as many errors as the moon has craters! (that's a lot of holes) I had the same trouble with BlueCloth before. I do wish gems would fail to install if they're not properly install. This is definitely a cause for many posts from Rails people. On OS X at least, this may be less of a trouble with the next version of the OS, since it should have much of these things installed in a good way. (we'll see ...) But I can blame mysql as well. It isn't the most friendly install either. I just hope this doesn't turn into one of those all day installs that leads me learning more about mysql internals than I want to know...
