I run Tiger on a Macbook. I installed Ruby and Rails by the DarwinPorts
method. I tried to run irb, and I get the following:
Macbook:~ aaron$ irb
dyld: NSLinkModule() error
dyld: Library not loaded: /opt/local/lib/libreadline.5.0.dylib
Referenced from: /opt/local/lib/ruby/1.8/i686-darwin8.6.2/readline.bundle
Reason: image not found
Trace/BPT trap
It turns out that readline is installed.
Macbook:~ aaron$ sudo port installed readline
Password:
The following ports are currently installed:
readline @5.0.005_0+darwin_8
readline @5.1.004_0 (active)
Macbook:~ aaron$
But when I try to uninstall either version, to reinstall it... they both say
they depend on ruby and postgresql8. So I'm stuck.
Any ideas?
Thanks,

The problem is that ruby was compiled when readline 5.0 was installed so it links against the 5.0 dylib. There are several ways to fix it:
1) Uninstall ruby and recompile it. Now it will find that readline 5.1 is installed and link against it
2) Make a symbolic link like so:
sudo ln -s /opt/local/lib/libreadline.5.1.dylib /opt/local/lib/libreadline5.0.dylib
Now it will find the dylib and hopefully it will work.
Solution 1) is cleaner but solution 2) is faster.
BTW: If you want to uninstall a port and you are really sure what you are doing you can do 'port -f uninstall <portname>'.
