I'm guessing you're talking about your ISP as your web host, if so, the
only way I know how to do it is to actually put the "use" statement in an
cgi script and see if it works. Like:
test.pl
----
#!/usr/bin/perl -w
use strict;
use CGI qw(:standard);
use CGI::Carp qw(fatalsToBrowser);
use ?????::Module;
print header, start_html("test"), h1("Add test.");

Where "?????::Module" is the one you need. Bit of a long way to go, but
the server will let you know if the module you need isn't installed.
If it's not, what you could do is:
1. Download and install the module on your home machine
2. Copy all the subroutines from the module (or just the subroutines you
actually need into your cgi script. Again, a long way to go, but it
worked for me. You could use:
perldoc -m ?????::Module > test.cgi
Substitute your own headers, and put your code after the subroutines,
delteing everything else. Should work the same the same as using the
module. In my case it worked fine with Sort::Fields
good luck,
