aloha todd

based on your original command line (something like <prompt> perl scan.pl ...)
i have to assume you're not using a *nix like os, which means i'm not in
a position to give you much assistance (beyond recommending you install
one or buy a mac ;-) kidding kindasorta). much of the stuff below is very
novice user oriented -- ignore it if you're beyond that stage.

on *nix like os, Date::Manip is an ordinary perl module, much like the
myriad gt modules. on *nix like os they are accessed via the perl @INC
array which is pre-defined in some perl config file. @INC can be altered
in any number of ways, in fact gt does so in the scripts with the directive:
use lib '..'; which allows the scripts to find the gt modules.

you can 'see' the default content of @INC using (maybe)
ras [ 10384 ] %    perl -e'print "@INC\n"'
/usr/local/lib/perl5/5.6.2/sun4-solaris /usr/local/lib/perl5/5.6.2 ...

you can alter @INC via command line with -I flag and argument
ras [ 10386 ] %    perl -I/usr/perl5/site_perl/5.8.4  -e'print "@INC\n"'
/usr/perl5/site_perl/5.8.4 /usr/local/lib/perl5/5.6.2/sun4-solaris ...

you can read all about your perl install via perldoc ... try something like
ras [ 10388 ] %    perldoc perl



if gt fails with date strings like --start '6 months ago' --end 'last friday'
you need to figure out where date::manip is and get that path into the
@INC used for gt.

and if you can figure out how to alter
perl -M"Date::Manip 99" -e 'exit;'
to work on your system and share it with me i will be better able to
assist others with similar issues in the future.
