Okay, got those installed…just used the following:
sudo apt-get install php5-sqlite
sudo apt-get -y install php-pear
sudo apt-get install php5-dev (required when I tried to install stem)
sudo pecl install stem
Now, the search seems to work, but I’m getting directory errors when I go to an article. In the package, there is (medline, for instance), there is a /en-medline_plus folder, and there’s a /var folder. Do I copy both of these, or just one of them (they appear to be the same thing), and do I need to keep the folder name, and copy to the web root?
