The perl_setup.com in the PCSI kit starts from the one generated at
configuration time in the source kit but it looks like there is an
automated edit that has gone haywire and duplicated the DEFINES. Thanks
for the heads up.

primarily there for use when installing from source where it specifies
the target location, which (since you haven't installed yet) isn't the
current location where the command procedure resides.
