Warnings from HTMLTidy : Return value was 126

I have installed the most recent HTMLTidy module and copied 'tidy' from the tidy.sf.net into the following location: /home/account/public_html/pulse/modules/htmltidy/bin/tidy

The path is actually /home/account/public_html/pulse/modules/htmltidy/bin/ and the file name is tidy

The system detects tidy and automatically generates the path as "/home/account/public_html/pulse/modules/htmltidy/bin/tidy"

It then gives the following erro message

HTMLTidy executable is not available. Found 'tidy' binary, but it didn't run right. /home/account/public_html/pulse/modules/htmltidy/bin/tidy -v failed to respond correctly

I am on a shared server runing CentOS Linux. I have googled but don't find a hit on Warnings from HTMLTidy : Return value was 126.

You help is much appreciated.
