Drush on Macbook Pro cannot read Dupal Correctly NOW RESOLVED!
RESOLVED. 9/22/2014

I began to discover that the previous method of attempting to change the 'alias' or otherwise redirecting Drush to use MAMP's PHP was the wrong way to go. Especially 'name-distorting' the original MacBook-OS-PHP so that Drush would opt for the MAMP-PHP was causing all kinds of problems with other software, as might be expected. I don't know how this method came to be recommended, but it appears that it is actually a pit-fall.

The way better approach (watch me eat my words in a few weeks), is to rather just upgrade the MacBook-OS-PHP to the same or nearly same version as the MAMP-PHP. Then it does not matter which version of PHP Drush or anything else uses because they are both the same. This overcomes all the issues and is not that difficult to accomplish. At least on my platform which is a MacBook-Pro (2008-Mavericks).

The way that I upgraded my MacBook-OS-PHP was by the CLI-command "curl -s http://php-osx.liip.ch/install.sh | bash -s 5.5".

This is a download from a group of developers in Germany which upgrades your PHP. Check out "http://php-osx.liip.ch/".

Once my System-PHP and MAMP-PHP were almost the same, all my issues with Drush went away. I undid all my 'aliases', 'redirects' and 'name-distortions'. So far all is working well.

Note that on my machine MAMP is using PHP-5.5.14 and my CLI reports with a "php -v" command that MacBook-OS is using PHP-5.4.30 though I am not sure that the version is accurate. In the write up on the PHP-Upgrade it mentions that the version might not be accurate.

By the way this does not OVERWRITE your previous PHP installation but rather just adds a newer installation and directs your system to use it.

I will update if there later prove to be drawbacks in this approach.
