searchd giving error "dyld: Library not loaded: libmysqlclient.18.dylib" on Mac

On Mac system, in one of my application using Thinking Sphinx. After installation while running searchd, it gives following errors:

$ searchd

dyld: Library not loaded: libmysqlclient.18.dylib

  Referenced from: /usr/local/bin/searchd

  Reason: image not found

Trace/BPT trap

-:sphinx-0.9.8 ror$ cd ..

-:Downloads ror$ l

-bash: l: command not found

Solution:
It's because unable to find the libmysqlclient library. Add the following to to your ~/.profile:

export DYLD_LIBRARY_PATH=/usr/local/mysql/lib/
and it will work fine
