Hello,
Does anybody know how to deal with this gem problem ?
Thanks a lot in advance for your help.
After trying to run gem update the message is:
gem update
Updating installed gems
Updating hpricot
Building native extensions. This could take a while…
ERROR: While executing gem … (Gem::Installer::ExtensionBuildError)
ERROR: Failed to build gem native extension.

*** 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.
