Which sub-version ? In my version, I have in rbconfig.rb CONFIG.each{|k,v| MAKEFILE_CONFIG[k] = v.dup} def Config::expand(val) val.gsub!(/\$\(([^()]+)\)/) do |var| key = $1 if CONFIG.key? key "#{Config::expand(CONFIG[\"#{key}\"])}" else var #^^^^^^^^^^ # Here the problem va`R' and not va`L' # end end val end CONFIG.each_value do |val| Config::expand(val) end The value of MAKEFILE_CONFIG and CONFIG are not expanded More now mkmf.rb use Config::MAKEFILE_CONFIG in 1.5, rather than CONFIG (in 1.4) Guy Decoux
