Unable to install sqlite3-ruby on Mac OS X 10.7.5

[natalia.v...@gmail.com]

Hello,

   I am trying to install sqlite3-ruby on Mac OS X (v10.7.5).  I get the following error:

> sudo ruby setup.rb config

….

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby /Users/con5pq/sqlite3-ruby/ext/sqlite3/extconf.rb 

setup.rb:472: warning: Insecure world writable dir /usr/local in PATH, mode 040777

checking for sqlite3.h... no

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).

*** /Users/con5pq/sqlite3-ruby/ext/sqlite3/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.

…..

    This is strange because mkmf.log says that header is actually found:

have_header: checking for sqlite3.h... -------------------- yes

"cc -E -I. -I/usr/lib/ruby/1.8/i486-linux -I/home/sderle/projects/geocoder/sqlite3-ruby/ext/sqlite3_api -I/usr/local/include  -D_FILE_OFFSET_BITS=64\

  -fno-strict-aliasing -g -g -O2  -fPIC    conftest.c -o conftest.i"

checked program was:

/* begin */

1: #include <sqlite3.h>

/* end */

    Can someone please help me with this?  Thank you!
