Environment : This relates to situations where make fails to finish due to errors and the SVN root is in a non-standard location.
The most common symptom will be that the make will fail with errors and looking through the output there will be two different paths where information is being pulled from. For example, you may see /home/myuser/svn/mercury as well as /root/svn/mercury.
Also, when checking the SVN and AMP versions they may show version mismatches.
Change the /root/svn directory in the command to point to your actual SVN directory.
Warning: Do not attempt to set the SVNDIR variable to an outdated SVN directory in an attempt to perform a downgrade, this could cause significant problems requiring a full reinstall.
