Why does rvm install ruby not work?

It is said on the Rails 3.2.9 blog that Ruby 1.9.3-p327 is recommended to be installed. But 

rvm install ruby-1.9.3-p327

actually gives an error, and the log says:

There is no checksum for 'http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p327.tar.bz2' or 'ruby-1.9.3-p327.tar.bz2', it's not possible to validate it. If you wish to continue with unverified download add '--verify-downloads 1' after the command.

But I checked http://ftp.ruby-lang.org/pub/ruby/1.9/ and the ruby-1.9.3-p286 has the same files as the p327. So where is the checksum located? Is it inside of the .bz2 file? So how should we install p327, is it just by

rvm install 1.9.3-p327 --verify-downloads 1

and is there security concerns, or are there other methods to install it safely?

First thing, make sure that your rvm version knows about this version by running rvm list known

On my machine, when I ran it the first time I got the following output for known MRI Rubies:

$ rvm list known
# MRI Rubies
[ruby-]1.8.6[-p420]
[ruby-]1.8.7-p370
[ruby-]1.8.7[-p371]
[ruby-]1.9.1[-p431]
[ruby-]1.9.2-p180
[ruby-]1.9.2-p290
[ruby-]1.9.2-p318
[ruby-]1.9.2[-p320]
[ruby-]1.9.2-head
[ruby-]1.9.3-preview1
[ruby-]1.9.3-rc1
[ruby-]1.9.3-p0
[ruby-]1.9.3-p125
[ruby-]1.9.3-p194
[ruby-]1.9.3-[p286]
[ruby-]1.9.3-head
ruby-head

So my version of rvm only knew about 1.9.3-[p286] as the most recent version 1.9.3 version.

I got the latest version of rvm with the following command:

$ rvm get stable

After that, the list of known MRI rubies was as follows:

$ rvm list known
# MRI Rubies
[ruby-]1.8.6[-p420]
[ruby-]1.8.7-p370
[ruby-]1.8.7[-p371]
[ruby-]1.9.1[-p431]
[ruby-]1.9.2-p180
[ruby-]1.9.2-p290
[ruby-]1.9.2-p318
[ruby-]1.9.2[-p320]
[ruby-]1.9.2-head
[ruby-]1.9.3-preview1
[ruby-]1.9.3-rc1
[ruby-]1.9.3-p0
[ruby-]1.9.3-p125
[ruby-]1.9.3-p194
[ruby-]1.9.3-p286
[ruby-]1.9.3-[p327]
[ruby-]1.9.3-head
[ruby-]2.0.0-preview1
ruby-head
