# Install/update dependencies for qmail-toaster suite of packages.
# This started as spamassassin/perl dependencies, and grew from there.

# change log
# 11/11/13 shubes - added perl-libwww-perl, removed LWP::UserAgent, HTTP::Date
# 07/26/12 shubes - Added gnupg for spamassassin (sa-update)
# 04/09/11 Jake   - Added routine to check for dependencies for the
#          base OS (ie: rpmbuild and such). Based off of
#          deps for CentOS, so probably needs testing for other distros.
#
# 07/29/10 shubes - created from code in qtp-newmodel
