Running OS X (10.9), I have a program called 'HEAD' in /Applications/XAMPP/xamppfiles/bin/, which is related to libwww-perl.

The OS also has an unrelated program called 'head' in /usr/bin/

Since the filesystem is not case-sensitive, and both of these directories are in my PATH, there is a conflict. I notice when I compile ffmpeg, it's using the xampp program when it should be using the OS program, and that's causing errors.

This is a known problem with case-insensitive HFS+ file systems. You're lucky you didn't overwrite head while installing LWP.

Two solutions:

  • Put /Applications/XAMPP/xamppfiles/bin into the PATH at a later stage. The system-default head will take precedence. Refer to HEAD with its full path if you must, or create a shell alias for it.

  • You should be able to rename HEAD into something else and just use that instead, depending on what calls it.
