*** It includes DB functionality on different platforms. ***
*** It includes a new pkg_add -u switch (and -r is old -u). ***
*** This package can be registered as a package. ***
This is a custom pkg_install:
1) configures for more db versions.
2) integrates a new package upgrade routine where it overwrites
instead of pkg_delete'ing first (see pkg_add man page)
3) pkg_add -r is the replace mechanism -- it is the old -u switch
4) pkg_add -u is the new overwriting upgrade option
5) currently the part to delete files no longer included after
upgrade is disabled (for now for testing)
