Comment(by watson1978@…):

 I guess that this issue is cause of ICU 4.0 which installed in Mac OS X
 10.6.[[BR]]
 When I used the ICU 4.4.2, this issue does not appear.

 Build the ICU
 {{{
 $ curl -O http://download.icu-project.org/files/icu4c/4.4.2/icu4c-
 4_4_2-src.tgz
 $ tar xvzf icu4c-4_4_2-src.tgz
 $ cd icu/source/
 $ ./runConfigureICU MacOSX --disable-renaming
 $ make
 $ sudo make install
 }}}

 Build the MacRuby
