Magento Cannot Initialize Index Process (No Locks Folder in Var)

Question

The issue:
When I try and reindex my local site, I get the error that Magento "cannot initialize the indexer process."

Other information:
- Upon trying to manually reindex the files through the terminal, I was made aware that pdo_mysql has not been installed.
- It is the "Product Flat Data" that needs to be reindexed.
- The problem is occurring on both the local and live copies of the site.
- This problem does not occur on other local copies of sites I work on.
- I do not have a "locks" folder in my /var folder.

Also, if it is important I have Magento 1.9.2.1 installed, am running through PhpStorm, am on a Mac, I run my local sites through MAMP.

Please help!

Try doing it programmatically. This way:

$indexCollection = Mage::getModel('index/process')->getCollection();
    foreach ($indexCollection as $index) {
      $index->reindexAll();
  }
