Resolution
 Ensure "bc" is installed on the IDM server. Once installed the patch upgrade should work as expected.
  
Cause
 Most linux distributions come pre-included with the bc utility which is a
 basic calculator utility. This utility is very helpful while evaluating
 complex calculations in bash scripts. The patch install script makes 
use of this utility and hence it is required to have the bc rpm present 
on the IDM server where the patch is being applied.
