estava a instalar o ruby-sqlite3 via gem, mas é-me reportado o seguinte output:

mathilda ~ # gem install sqlite3-ruby Building native extensions. This could take a while... ERROR: Error installing sqlite3-ruby: ERROR: Failed to build gem native extension.

/usr/bin/ruby extconf.rb install sqlite3-ruby checking for fdatasync() in -lrt... no checking for sqlite3.h... no

make make: *** No rule to make target `ruby.h', needed by `sqlite3_api_wrap.o'. Stop.

Gem files will remain installed in /usr/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.4 for inspection. Results logged to /usr/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.4/ext/sqlite3_api/gem_make.out

e tenho estes rpm's instalados:

mathilda ~ # rpm -qa | egrep 'sqlite' python-sqlite-1.1.7-1.2.1 sqlite-devel-3.3.6-2 sqlite-3.3.6-2 mathilda ~ # rpm -qa | egrep '(ruby)|(irb)' rubygem-rake-0.7.3-2.el5 ruby-irb-1.8.5-5.el5_2.5 rubygem-actionmailer-2.1.1-1.el5 ruby-libs-1.8.5-5.el5_2.5 ruby-devel-1.8.5-5.el5_2.5 ruby-ri-1.8.5-5.el5_2.5 rubygems-1.2.0-2.el5 rubygem-activeresource-2.1.1-1.el5 ruby-1.8.5-5.el5_2.5 ruby-rdoc-1.8.5-5.el5_2.5 rubygem-activesupport-2.1.1-1.el5 rubygem-activerecord-2.1.1-1.el5 rubygem-actionpack-2.1.1-1.el5 ruby-docs-1.8.5-5.el5_2.5 rubygem-rails-2.1.1-2.el5

e o sqlite3.h está no sistema. mathilda ~ # find /usr/ -iname *sqlite3.h* /usr/include/sqlite3.h

alguém sabe como resolver isto?
