geeky ninja: Installing ruby 1.9.2 with rvm

I've been having trouble installing ruby 1.9.2 with rvm on Mac OS X.
Although there are lots of great blog posts with solutions, for some reason, none of them worked for me.

The rvm page and many posts say to pass --with-iconv-dir to rvm install.
However, I kept getting errors about Tcl/Tk not being 64-bit, and iconv also not being 64-bit.
Why would it be complaining about iconv, especially since I used rvm to install it?

	ld: in /usr/local/lib/libiconv.2.dylib, missing required architecture x86_64 in file
	collect2: ld returned 1 exit status
	make[1]: *** [../../.ext/x86_64-darwin10.5.0/tcltklib.bundle] Error 1
	make: *** [mkmain.sh] Error 1

I noticed the config.log spit this out:

configure: WARNING: unrecognized options: --with-iconv-dir

I tried many options that were in configure, but none of them pointed the makefile to rvm's version of iconv.

So I took a look at /usr/local/lib/libiconv.2.dylib and noticed it was a symlink.
Perhaps this is taking the easy way out, but I backed it up by renaming it, and relinking that to the version inside $rvm_path.

After that, I recompiled by running:



 rvm install 1.9.2 -C --enable-shared

Success!
The output:
