problem in installing gems

I have problems in installing gems that need to be compiled locally like hpricot.
others gems have no problem but I get this error whenever I’m trying to install a gem that need to be compiled:

• extconf.rb failed *
  Could not create Makefile due to some reason, probably lack of
  necessary libraries and/or headers. Check the mkmf.log file for more
  details. You may need configuration options.

Provided configuration options: —with-opt-dir —without-opt-dir —with-opt-include —without-opt-include=${opt-dir}/include —with-opt-lib —without-opt-lib=${opt-dir}/lib —with-make-prog —srcdir=. —curdir —ruby=C:/PROGRA_1/BITNAM1/ruby/bin/ruby

Gem files will remain installed in C:/PROGRA_1/BITNAM1/ruby/lib/ruby/gems/1.8/gems/hpricot-0.6.161 for inspection.
Results logged to C:/PROGRA_1/BITNAM1/ruby/lib/ruby/gems/1.8/gems/hpricot-0.6.161/ext/fast_xs/gem_make.out

can anyone shed some light?
