I always thought that links to real directories were pretty much

I have a Ruby on Rails application running on a FreeBSD server. All
Rails apps use the same directory structure, that consists of an
application directory, plus a number of subdirectories. One of
these sub directories is called 'config'.
I would like to move this config directory out of the main Rails
app directory, and then add a link from the app directory to the
moved config directory.
so:
app --> config
will become
app --> config(link) --> config
Basically, what I'm doing is:
cd ~/app # now in directory with real 'config' dir
mv config ~/shared/config
ln -s ~/shared/config config
That moves the directory and creates a functional link to it (I
tested it), but Rails doesn't like it and refuses to run the app.
The permissions are correct, I believe:
[mas...@on:current]> ls -l
total 34
... snip ...
drwxrwxr-x 3 master master 512 Mar 16 11:06 bin
drwxrwxr-x 3 master master 512 Mar 16 11:06 components
lrwxr-xr-x 1 master master 26 Mar 16 11:07 config -> /home/
master/shared/config
drwxr-xr-x 4 master master 512 Mar 16 11:06 db
etc...
So, I guess a link is NOT exactly equivalent to a directory. At
least not the way I am doing it.
I'm guessing I'm making a real newbie mistake, so if anyone can set
me straight, I'd appreciate it.

A little more information on this... from the Rails log, I can see
that a Ruby script in the config directory cannot load ('require') a
needed file because it can't find it:
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in
`gem_original_require': no such file to load -- application
(MissingSource File)
It looks like this require statement is using a relative path, like
'../path/to/file'. Does '..' not work properly with a soft link? In
other words, '..', should mean ~/app, but since the config directory
is really in '~/shared', perhaps '..' translates to '~/shared'? That
would cause the problem finding the file.
Is there a way around this problem?
Digging in man ls, right now..
