Description

This is my first bug, and I'm not very experienced with Java (I'm more on the ruby side) - this said, I'm using jruby to perform console-process automation and so the 'pty' library (of stdlib) is really important for my work.

The 'pty' library does not work in jruby-complete-1.6.0.RC1.jar nor in jruby-complete-1.6.0.RC2.jar.

This error was verified in Windows Vista and Sun Solaris (same in both OSs), using the jruby-complete-X.jar versions of Jruby.
The error only affects the jruby-complete-X.jar version; in the binary Jruby .tar.gz or .zip versions the 'pty' library works normally

Bellow are left the errors messages of require 'pty' in jruby-1.6.0.RC1 and jruby-1.6.0.RC2

I have a similar error on ubuntu with jruby-1.7.0
Without the package libc6-dev:

irb(main):001:0> require 'pty'
LoadError: Could not open library 'libutil' : libutil: cannot open shared object file: No such file or directory. Could not open library 'libutil.so' : libutil.so: cannot open shared object file: No such file or directory
	from /home/jenkins/.rvm/rubies/jruby-1.7.0/lib/ruby/shared/ffi/library.rb:82:in `ffi_lib'

With the package libc6-dev the require succeeds without a hitch

libc6-dev installs the following symlink, which is likely why it works:

/usr/lib/x86_64-linux-gnu/libutil.so: symbolic link to `/lib/x86_64-linux-gnu/libutil.so.1'
