WordPress Sphinx Search Plugin

I am using WordPress Sphinx Search Plugin (version 2.1). Sphinx installed successfully. when indexing starts it shows the following error message.

Installation: Sphinx installation error, try to run this command manually in Terminal:
Command: ./configure –with-mysql –prefix=/home/spinning/public_html/wp-content/uploads/sphinx 2>&1 at the directory:/home/spinning/public_html/wp-content/uploads/sphinx/sphinx-0.9.9
try running it with sudo if it doesn’t work

Anybody can tell me the solution.
