Anyone please help..
How can I fix the following error:
dyld: Library not loaded: /usr/local/lib/libgdbm.4.dylib
Referenced from: /usr/local/bin/zsh
After searching for a long time, this solved it for me:
brew reinstall ncurses
I suspect you are running into problems while working with Homebrew on MacOSX. I am actually saying this because I have just run into the exact same situation.
The problem comes after upgrading my MacOSX version to Maverick from Mountain Lion while having already installed Homebrew (of course this may apply to previous and future upgrades). After the upgrade you will need also:
Run an update on Homebrew
brew update
Run a general upgrade of your Homebrew packages
brew upgrade
Make sure you do not have any other problems on your installation
brew doctor
Finally you may find that certain packages are failing due to missing libraries, which seems to be the case you are describing. The idea here is to reinstall the library missing using the brew command.
In your case you would need to reinstall the gdbm library by performing the next steps on your terminal:
brew uninstall gdbm
brew install gdbm
That should fix it.
