/supp, I'm assuming, is a virtual directory denoting the search path 
for all lib roots... I get the same error. here:

First, looking in relevant directories:
   % ls -l /System/Library/PrivateFrameworks/readline.framework
   total 16
   lrwxr-xr-x  1 root  wheel   26 13 Nov 12:50 Resources -> 
Versions/Current/Resources
   drwxr-xr-x  4 root  wheel  136 23 Sep 23:44 Versions
   lrwxr-xr-x  1 root  wheel   26 24 Sep 14:21 readline -> 
/usr/lib/libreadline.dylib
   % ls -l /usr/lib | grep readline
   -r-xr-xr-x   1 mark  staff   324308  6 Sep  2003 libreadline.4.3.dylib
   lrwxr-xr-x   1 root  admin       21 24 Sep 08:40 libreadline.4.dylib 
-> libreadline.4.3.dylib
   -rw-r--r--   1 mark  staff   487060  6 Sep  2003 libreadline.a
   lrwxr-xr-x   1 root  admin       21 24 Sep 08:40 libreadline.dylib -> 
libreadline.4.3.dylib

Next, testing readline:
   % ruby -rreadline -e'print'
   % sudo mkdir /usr/lib/lrl
   % sudo mv /usr/lib/libreadline.* /usr/lib/lrl
   % ruby -rreadline -e'print'
   dyld: ruby can't open library: /supp/lib/libreadline.4.3.dylib  (No 
such file or directory, errno = 2)
   zsh: trace trap  ruby -rreadline -e'print'

There is no /supp directory, so I have to assume that it's virtual. 
Also, the only readline in readline.framework/ is a symlink to the one 
in /usr/lib. I'm thinking that this means that it was put there by 
Apple, since, I can't imagine any packages deleting files in 
/System/Library/PrivateFrameworks...

Still, I'll need to look into this, to see if there's a good solution. 
It seems that any Ruby package will either have to depend on the 
developer tools being installed, or come with a copy of readline to 
install in /usr/local/lib. I think over the weekend I can look into it 
more...
