###################################################
# A basic cascade-make to install the DBD::mysql v 4.033 perl package to work with the GreenstoneSQLPlugin/Plugout
#
# Requires an internet connection to download required packages etc
#
# No dependencies
#
#
# Compiling AND INSTALLING of all packages takes place in the temporary cpan/tmp folder. A select subset of the compiled/installed
# products are then copied into their final destinations: lib/../<pkg> is copied into cpan, and lib/../auto/<pkg> is copied into cpan/auto
#
