Thank you, Jan-Pieter!
We believe your's is the definitive response. We believe we fixed the problem by editing
Unix/Syslog.pm and removing the items from EXPORT that were not defined in our environment. We
believe none of those were used in mimedefang. Following is the segment showing what we changed:
=====================
# The following has been modified from the distribution Syslog.pm that had originally
# been installed from the source. Comments include George's commentary along with the
# original code. The uncommented lines are the modified code.
# Items to export into callers namespace by default. Note: do not export
# names by default without a very good reason. Use EXPORT_OK instead.
# Do not simply export all your public functions/methods/constants.
# NOTE: the following are the original macros. Of these LOG_AUTHPRIV, LOG_FTP,
# LOG_PERROR, LOG_FAC, LOG_PRI, and LOG_MAKEPRI are not defined on Solaris
# and so generate an error. Those are removed from the non-commented text
# below. GFD 15 Feb 2011
