Hello,

I have downloaded ruby-1.91-1-p376, configured and built

(./configure --with-pthreads; make;make install)

downloaded rubygem 1.3.5, unpacked, then

ruby setup.rb

And when I run

# gem install rails

I get the following error:
# gem install rails
/usr/local/lib/ruby/site_ruby/1.9.1/rubygems/package.rb:10:in `require': no
such file to load -- zlib (LoadError)

#

when I check nohup.out from the make and grep for zlib I see the following:
# grep zlib noh*
nohup.make:compiling zlib

And checking the nohup.out from the install I get the following for the
required packages in 'package.rb' (e.g., stringio and yaml)

nohup.out:ext/zlib/zlib.c:
MCCCCCCCCCCCCCCCCCCmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm
# grep zlib .installed*
/usr/local/share/ri/1.9.1/system/Zlib/zlib_version-c.yaml
# grep stringio .installed*
/usr/local/lib/ruby/1.9.1/yaml/stringio.rb
/usr/local/lib/ruby/1.9.1/powerpc-aix5.3.0.0/stringio.so
# grep fileutils .installed*
/usr/local/lib/ruby/1.9.1/fileutils.rb

It looks like zlib has been compiled, but not installed?

These are the zlib files in the package area:
# pwd
/data/prj/ruby-1.9.1-p376
# find . | grep zlib
./ext/zlib
./ext/zlib/.cvsignore
./ext/zlib/doc
./ext/zlib/doc/zlib.rd
./ext/zlib/extconf.rb
./ext/zlib/zlib.c
./ext/zlib/mkmf.log
./ext/zlib/Makefile
./.ext/rdoc/Zlib/zlib_version-c.yaml
./test/zlib
./test/zlib/test_zlib.rb

These are the 'zlib' files in the installed area:
# cd /usr/local
# find . | grep zlib
./share/ri/1.9.1/system/Zlib/zlib_version-c.yaml

Suggestions welcome.
