@jinweno, can you provide more info about your environment? how did you install this jruby?

my ruby:
jruby 1.6.7 (ruby-1.8.7-p357) (2012-02-22 3e82bc8) (Java HotSpot(TM) 64-Bit Server VM 1.6.0_29) [darwin-x86_64-java]

I don't have a 32bit install/machine to test this :(

You can drop your vm to 32 bit with JAVA_OPTS="-d32" and run JRuby on 1.9 mode with JRUBY_OPTS="--1.9"

the gem can be installed on MRI 1.9.3-p125:

$ ruby -v
ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-darwin11.3.0]

$ gem install posix-spawn

@jingweno same thing running on 32bits - I couldn't reproduce
