Upgrade to Pear 1.3.1

I had an older version of Pear and had no problems installing new packages via the pear install package_name command. I upgraded to the new version of Pear because one of the packages required it. Now, I am getting the following error whenever I try to install anything: Fatal error: Call to undefined function: getopt2() in c:\php\pear\system.php on line 71. I did a Google and searched the archives for this list, but didn't find a similar occurence. I found one, but it was in a foreign language with no response. I am writing an ebook and it has a section on Pear, so I am stuck. Would appreciate any help. Best, Meryl www.meryl.net
