in reply to installable Compress::Zlib

No. Compress::Zlib contains a binary component that needs to be compiled with exactly the same C compiler that your Perl was compiled with. Without knowing the operating system, Perl version and C compiler of your host, it is not possible to create a ready-to-install version for you.

If you have shell access on your host, the following command typed in the terminal will output all necessary information:

perl -V

If you don't have shell access, you will need to upload a CGI script that does the equivalent. I haven't done much CGI programming lately, so I don't have the easy method for this handy - the following untested code should do in a CGI what perl -V does on the commandline:

#!/usr/bin/perl -wT use strict; use Config(myconfig); print "Content-Type: text/plain\r\n\r\n"; print myconfig();
