$ bundle install: Failed to create custom gem extension

Using Snow leopard, Rails 3.0.3, ruby ​​1.9.2p0 and RVM. When I try to install the package, I get:

You are missing some of the sqlite related libraries on your system. This is a common problem with gems, which depend on the libraries that must be installed on your computer. try installing libsqlite3-dev.

I ran into almost this problem (Snow Leopard, Ruby1.9.2-p0, RVM, Rails 3.1.0rc4, with installed developer tools) and resolved it by updating to a newer level of Ruby fix.

Using RVM, you should write:

 rvm upgrade ruby-1.9.2-p180 ruby-1.9.2-p0

(180 is the current patch, but when you try it may be a newer one). Use the stable version of the version named here: http://www.ruby-lang.org/en/downloads/ )

Try:

 gem "sqlite-ruby", "~> 1.3.1"

You may have problems because you are on Ruby 1.9. This gem is said to work with 1.9:

Use the 'sudo bundle install' as you try to write your own extensions to system directories.
