Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

checking for sqlite3.h... no
sqlite3.h is missing. Try 'port install sqlite3 +universal',
'yum install sqlite-devel' or 'apt-get install libsqlite3-dev'
and check your shared library search path (the
location where your sqlite3 shared library is located).
*** extconf.rb failed ***
