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.

Has anyone figured out what XAMPP actually uses its HEAD program for? I was very confused when I tried to head a file today and got a help dialog about HTTP requests. – alexw – 2016-04-07T03:17:04.963
I did rename HEAD, but I don't know if this will cause problems. It's part of the default XAMPP installation, so I have no idea when it would be called. – Elliott B – 2013-10-23T19:30:20.843
Do you necessarily have to have the bin in your PATH? AFAIK only xamppfiles/xampp is the executable you'd really need. – slhck – 2013-10-23T19:34:48.397
I really don't know, that's a question for the XAMPP developers. There are lots of binaries in there. Since the default XAMPP installer adds this directory to the PATH, I would guess that their code does not use hard-coded paths to binaries. – Elliott B – 2013-10-23T21:07:10.397
Change PATH temporarily, maybe? – gronostaj – 2013-10-23T10:59:22.653
