Question
I'm attempting to install Ruby on Rails 3 on RHEL 6. I've 'yum install' sqlite and sqlite-devel (which is sqlite3 on RHEL6). As you can see, sqlite3.h does exist where it needs to be. 'gem install sqlite3-ruby' still doesn't work, for some reason.
SQLite3:
[root@rhel6base gems]# yum list sqlite-devel
Installed Packages
sqlite-devel.x86_64 3.6.20-1.el6 @local
Available Packages
sqlite-devel.i686 3.6.20-1.el6 local
[root@rhel6base gems]# ls -l /usr/include/sqlite3.h
-rw-r--r--. 1 root root 268966 Nov 24 2009 /usr/include/sqlite3.h
Gem install:
[root@rhel6base gems]# gem install sqlite3-ruby
Building native extensions. This could take a while...
ERROR: Error installing sqlite3-ruby:

sqlite3.h is missing. Try 'port install sqlite3 +universal'
or 'yum install sqlite3-devel' and check your shared library search path (the
location where your sqlite3 shared library is located).
*** 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

--without-sqlite3-dir
--with-sqlite3-include
--without-sqlite3-include=${sqlite3-dir}/include
--with-sqlite3-lib
--without-sqlite3-lib=${sqlite3-dir}/lib
Gem files will remain installed in /usr/lib64/ruby/gems/1.8/gems/sqlite3-1.3.3 for inspection.
Results logged to /usr/lib64/ruby/gems/1.8/gems/sqlite3-1.3.3/ext/sqlite3/gem_make.out
PS: It'd sure be nice to create a 'rhel6' tag, but I don't have enough reputation.
Solution
It turns out you have to have gcc installed for 'gem install sqlite3-ruby' to work. It will never explicitly tell you that gcc isn't found (even the log file doesn't mention it).
OTHER TIPS
I've 'yum install' sqlite and sqlite-devel (which is sqlite3 on RHEL6)
That's not true. From my RHEL6 server installation:
# yum search sqlite
...
sqlite.i686 : Library that implements an embeddable SQL database engine
sqlite-devel.i686 : Development tools for the sqlite3 embeddable SQL database engine
...
You are missing sqlite3.h file. If you need a file that should be in RHEL6 repositories always use this command to find it:
# yum provides /usr/include/sqlite3.h
sqlite-devel-3.6.20-1.el6.i686 : Development tools for the sqlite3 embeddable SQL database engine
Repo : rhel-i386-server-6.0.z
Matched from:
Filename : /usr/include/sqlite3.h
Therefore install sqlite-devel package and you will be able to compile successfuly. Good luck.
