I reinstalled IO-1.2301 and Compress-Zlib but this did not restore functionality to PDF::API2. Running one of the 'example scripts' provided in the documentation for Zlib.pm resulted in an error involving 'dualval' which turned out to be a subroutine in Scalar::Utils which is 'use'd by Zlib.pm. Reinstalling Scalar-List-Utils-1.19 fixed that problem and also (thankfully) restored PDF::API2. > I am not sure what happened to Scalar::Utils when the security patch was applied but I have a suspicion it might have been deleted? Whilst these measures have fixed my immediate problems with Perl I fear we may yet see some more bugs emerging from the woodwork as time goes on.
