I've 10.10 on x64 here, I followed the guide with some exceptions and it
worked out of the box.

The exceptions were: I didn't use "rvm pacakge ..." (why should I?), nor
the extra parameters to "rvm install ...". And for "gem install" I left
out the --pre, it's been released in the meantime. In other words:
compiling ruby 1.9.2-head worked.

That's weird, in my logfile it looks like this:

generating enc/trans/utf_16_32.c ...
converter for from_UTF_16LE
converter for from_UTF_32LE
converter for from_UTF_16BE
converter for from_UTF_32BE
converter for from_UTF_8
done.  (0.03user 0.01system 0.02elapsed)
ffi.h is missing. Please install libffi.
ossl_hmac.c: In function ¡Æossl_hmac_hexdigest¡Ç:
ossl_hmac.c:162: warning: comparison between signed and unsigned integer
expressions

I.e. it just goes on with trying to compile ffi, etc.

I'd would give it a try without those extra parameters.
