thanks Eric.

you gave me a fantastic bullet to solve problems.

There is also zlib library in .ext/ia64-hpux11.31.

I copied it in to /usr/local/lib/ruby/site_ruby/1.8/ia64-hpux11.31/.

then I got beautiful gem's results. :)

However, I don't understand why this zlib library didn't be copied =20
with the other libraries.
