$ bundle install: Failed to build gem native extension

Using Snow leopard, Rails 3.0.3, ruby 1.9.2p0 and RVM. When trying to install bundle I get:

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

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

Using RVM, you'd write:

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

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

Try:

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

You may be having issues because you're on Ruby 1.9. This gem is said to work with 1.9:

Use 'sudo bundle install' since native extensions try to write in system directories.

1. sudo -s
2. export ARCHFLAGS='-arch x86_64'
3. export PATH=/Library/PostgreSQL/9.1/bin:${PATH}
4. gem install pg
