I’m looking into building this with the latest tarball of REE source. When I was doing so I hit

installer.rb:428:in `chdir’: No such file or directory – /var/tmp/ruby-enterprise-1.8.7-2010.02-root-afairley/usr/local/lib/ruby/gems/1.8/gems (Errno::ENOENT)
from installer.rb:428:in `install_useful_libraries’
from installer.rb:66:in `start’
from installer.rb:696
error: Bad exit status from /var/tmp/rpm-tmp.59788 (%build)

It looks to me like the problem is a missing if guard

+if @install_useful_gems
Dir.chdir(”#{@destdir}#{@prefix}/lib/ruby/gems/1.8/gems”) do
if !Dir["sqlite3-ruby*"].empty?
# The sqlite3-ruby gem installs files with wrong
# permissions. We fix this.
sh “chmod -R g+r,o+r,o-w sqlite3-ruby*”
end
end
+end
