See my previous message, you need to make a a directory "Date" in your 
working directory and place Pcalc in there

 use Date::Pcalc qw(Delta_Days Add_Delta_Days Date_to_Days leap_year 
check_date);
ok, now we get to the nub of the crisis.

The File is Pcalc.pm, but the package line says

	package Date::Pcalc;

cf:
<http://search.cpan.org/src/STBEY/Date-Pcalc-1.2/Pcalc.pm>
what seems to have happened is that perl FOUND the file
Pcalc.pm, and looked in it, as you asked, with your
	use Pcalc.pm

for the package Pcalc - to import the LIST that you
have provided it. But of course the File does not
have such a package in it, and hence could not import
any of those symbols.
        /some/dir/
                foo.cgi
                Date/Pcalc.pm
thus when the foo.cgi is invoked, the

	use Date::Pcalc qw(Delta_Days Add_Delta_Days Date_to_Days leap_year 
check_date);

line will look in the sub_directory Date for a
file Pcalc.pm and read it for a package named
	package Date::Pcalc;

to look for the LIST of symbols to resolve...
