python -> perl help urllib.urlopen

[Robert]

is there some Perl veteran here. for some odd reason I need to translate a
small python cgi script containing

   import cgi,urllib
   ...
   print urllib.urlopen( targeturl, post ).read()

to Perl. for standalone Perl I found

   use CGI;
   require("url_get.pl");
   ...
   print url_get( $targeturl . "?" . $post);

working, but it doesn't work in a cgi script - url_get not there (mod_perl,
path-problems, ...?). And I cannot rely on more than standard perl
installation on the web server. obviously one cannot "use url_get;" like
"use CGI;"

those perl modules, usage, path and docu I do not come through. What would
be a likely solution?
