Image all of the files are symlinked back to the original sources, one
by one, not just
the top level directory.

I don't know what you mean by a "symlink farm". Is the PEAR directory a
symlink to
somewhere else or is it more complex than that? I'm just trying to
figure out how to
replicate this properly.

Description:
------------
Because of the liberal use of the __FILE__ magic constant,
which resolves symlinks, PHP code sniffer will not run.

Also, in some places there is code like this ...

if (is_file(dirname(__FILE__).'/../CodeSniffer/CLI.php') ===
true) {
     include_once dirname(__FILE__).'/../CodeSniffer/CLI.php';
} else {
     include_once 'PHP/CodeSniffer/CLI.php';
}

note that there is 'PHP' prefixed in the include_once statement.

But in the autoloader, there is no PHP prefixed to the file name
to be loaded, so you need to add various combinations to the
include_path of the interpreter to try and get this to work.

However, it will finally barf on

Fatal error: Uncaught exception 'UnexpectedValueException'

which cannot be worked around
