问题
Using Rails, whenever I try to do anything like "bundle install" or sudo gem install someGem, I get these same errors about sqlite3. I've tried both
sudo port install sqlite3 +universal
and
sudo port install rb-sqlite3 +universal
But neither has helped. Here is the error:
cmu-435163:photoGlass dpieri$ sudo gem install taps
Password:
Building native extensions.
This could take a while...
ERROR: Error installing taps:
ERROR: Failed to build gem native extension.

checking for sqlite3.h... yes
checking for sqlite3_libversion_number() in -lsqlite3... no
sqlite3 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

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/sqlite3-1.3.3 for inspection. Results logged to /Library/Ruby/Gems/1.8/gems/sqlite3-1.3.3/ext/sqlite3/gem_make.out
UPDATE: I found the mkmf.log file and here are its contents:

回答1:
Figured it out:
Did "which -a ruby" and "which -a sqlite3" and "which -a gem" to realize I had two or three versions of each
Use port to uninstall all the versions of Ruby, Sqlite3, and rubygems it had installed
Manually uninstall the other sqlite3 that was not along the same path as Ruby and Rubygems
Once Ruby, Rubygems, and Sqlite3 were all along the same bath (usr/bin) it all works fine again.
