Comment(by lsansonetti@…):

 Thanks for the quick patch! I merged it into my local repository and
 verified that the bug disappeared, and that YAML specs still pass as
 before. Please commit :)

 Now, installing the gsl gem fails with a different error:

 {{{

 Building native extensions.  This could take a while...
 ERROR:  Error installing gsl:

 I remember people reporting that narray won't compile with MacRuby. I
 believe the extension uses too much APIs that we don't support (like the
 RCLASS macro to access fields).
