From a's point of view, there is no c. But this works fine. Observe:
https://gist.github.com/4259909Each module can load whatever is in its node_modules folder (or
parents), no matter where the module lives. Then that module, in its
actual realpath home, can load whatever is in its node_modules folder
(or parents), no matter where they actually live.
This is required because of the way that executables are typically
linked. On Unix, you have something like:
/usr/local/node_modules/foo/bin/foo.js
which does `require("../lib/foo-internals.js")`.
That script is linked to
/usr/local/bin/foo
If we didn't realpath, then it'd be looking for
/usr/local/lib/foo-internals.js instead of
/usr/local/node_modules/foo/lib/foo-internals.js.
Does that make sense?

Consider this structure:
a/main.js
a/node_modules/b/index.js --> /b/index.js
b/index.js
b/node_modules/c/index.js --> /c/index.js
$ cat /a/main.js
require('b');
$ cat /b/index.js
require('c');
$ node a/main.js will fail to load 'c', because (as described in
http://nodejs.org/api/modules.html) it resolves symlinks and then does look
up relatively to the file content - symlink destination (not the symlink
path).
What are the reasons for this behavior ? I would expect otherwise.
Then, if you wanted to resolve deps relatively to the symlink destination,
you would create symlinks to directories, rather then individual files.
I'm asking, because the current behavior makes it very difficult to enable
local modules with our build tools + scm.
Thanks a lot for help,
V.
