Subject: [BUG] latest ruby 1.8.2 cvs breaks rubygems-0.8.1

/data/ruby/bin/ruby -v         
ruby 1.8.2 (2004-10-19) [sparc-solaris2.8]

gives the following error

data/ruby/lib/ruby/site_ruby/1.8/rubygems/package.rb:74:in `new_from_stream': method `unpack' called on terminated object (0x3c4c80) (NotImplementedError)

        from install.rb:148

This happens on win32 ruby (same version) as well,
so the bug is platform independent.

this bug is caused by the latest change to zlib.c.  
if I do

cvs diff -u -r1.7.2.7 -r 1.7.2.6 zlib.c > zlib.patch
patch < zlib.patch

rubygems installs ok. So either rubygems do not use zlib correctly or this
change is invalid.
