I, also, can't installed hpricot on Windows/XP, and I have the latest Ruby
installed:
C:\>ruby -v
ruby 1.9.1p0 (2009-01-30 revision 21907) [i386-mingw32]

C:\>gem install hpricot
Building native extensions.  This could take a while...
ERROR:  Error installing hpricot:

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:
