Bug #1960: errors in configure on AIX
http://redmine.ruby-lang.org/issues/show/1960

Author: Ittay Dror
Status: Open, Priority: High
ruby -v: ruby-1.8.6-p383

running on AIX 5.2, with:
./configure CC=cc --prefix=/opt/build/ruby CFLAGS='-g -qlanglvl=extc89 -q32'

i get:
./configure[17927]: /ruby:  not found
./configure[17927]: ${exec_prefix}/lib:  not found
./configure[17937]: /ruby/site_ruby:  not found
./configure[17937]: ${exec_prefix}/lib:  not found


but configure finishes. later (after make, make install) when trying to install rubygems i get 
./lib/rubygems.rb:10:in `require': no such file to load -- thread (LoadError)


which may be related to the previous error
