I swear, I have seen all the discussions of installing Ruby on stackoverflow...NOTHING helped. I have Xcode 4.1 installed as well as rvm 1.16.19.
libksba is installed.
There's SOME version of Ruby installed somehow but I don't know which version -- because if I execute ANY kind of Ruby command -- "ruby" by itself, "ruby --version," whatever, I get no response, and to get a prompt I have to ctrl/c.
Using RVM or not, whenever I try to install ANY version of Ruby, I get this output:
Error running 'env LDFLAGS=-L/opt/sm/pkg/active/lib CFLAGS=-I/opt/sm/pkg/active/include CPATH=/opt/sm/pkg/active/include -L/Users/Dauber/.rvm/usr/lib ./configure --enable-shared --disable-install-doc --prefix=/Users/Dauber/.rvm/rubies/ruby-1.9.3-p286', please read /Users/Dauber/.rvm/log/ruby-1.9.3-p286/configure.log
There has been an error while running configure. Halting the installation.
ruby-1.9.3-p286 is not installed.
Here's the output from the aforementioned configure.log:

See `config.log' for more details.
Now, a weird thing is that there's no file ANYWHERE in the system called "config.log," so I can't "see" it "for more details."
Another weird thing...I've compiled dozens of C programs on this machine using gcc and gcc-4.2 -- and I just tried AGAIN and they work fine, so I don't know exactly what the deal is there...
I've tried installing from https://github.com/kennethreitz/osx-gcc-installer to no avail; it made absolutely no difference.
This is all on my MacBook, running OSX 10.7.5. What's weird is...I've had ZERO problems on my iMac running the exact same version of Lion...in fact, I didn't even NEED to install Ruby - it happened to have 1.9.2 already on it; I just needed to add Rails and all worked perfectly...what the heck is so different that I can't get this stuff working on my MacBook???
AFTER PRUSSWAN'S LINK: Long story short, the other post prusswan linked to mentioned that there's a bug in the Rails installer and that /etc/rvmrc needed to be changed. I made the changes but got the exact same error message as before when I tried to install ruby. This is what configure.log says now, though:
