hi, all.
after installing ruby 1.8.7.p72 successfully, I tried to install rubygems.1.3.1.
It seems to be normally installed.
but, when I execute it, the errors is generated.
#> gem update
/usr/local/lib/ruby/site_ruby/1.8/ia64-hpux11.31/zlib.so: dlsym: Unknown symbol Init_zlib - /usr/local/lib/ruby/site_ruby/1.8/ia64-hpux11.31/zlib.so (LoadError)
actually, this is not a error log what I first met.
first error log is "no load error - zlib".
to resolve this problem, I trace the zlib location ruby wants. the one of them is "/usr/local/lib/ruby/site_ruby/1.8/ia64-hpux11.31" here.
I make a symbolic link by using /usr/local/lib/libz.so.1.2.3 under site_ruby/1.8/ia.......
wow. I am still in problems.
this time ruby cannot find "zlib.rb". I am not sure this is main reason gem is failed. but it could be a reason.
the procedure to execute gem binary is extremely hard. :-<
this is mkkf.log in ruby1.8.7p72/ext/zlib.

hmn, could be this a kind of clue ?

This won't work as /usr/local/lib/libz.so is not a ruby extension. The ruby zlib extensions loads this file.

These are both ok (in the first instance, deflateReset is probably a macro).
Did you get a zlib.so built? In your ruby checkout:
$ find .ext -name "*zlib*"
If you didn't include your entire mkmf.log

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 with the other libraries.
