When it comes to manually configuring compiled applications on my systems, I am a minimalist, meaning that I always try to get away with the bare bones settings. Once in a great while this will come back to haunt me. In starting up a new project, I came across an issue where the Magento install process was throwing a fatal error regarding a ‘hash’ function (Zend Framework actually needed it). So I had to recompile with `–enable-hash` setting. Be sure to run a make clean before configure, otherwise your new setting won’t be picked up.
