Something is wrong with the syntax though, and I can't understand what: 
open my $up, "<", "$_[0]" or die "Something went wrong: ".$!; binmode 
+$up;
my $ck = Digest::MD5->new; $ck->addfile($up); close $up;
my $us = HTTP::Headers->new; $us->header(Content_Type => 'multipart/fo
+rm-data');
my $req = HTTP::Request->new('POST',"https://".$server."/file_bucket_f
+ile/md5/".$_[1]."/".$ck->hexdigest, $us, [ file => ["$_[0]"] ]);
print Dumper($req);
my $res = $ua->request($req);
die "Something went wrong: ".$res->status_line unless $res->is_success
+;

perl -wc file doesn't complain, but when running I get "Can't call method "request" on an undefined value ". $req is defined, and shown on the line above, but the code doesn't get to the "something went wrong" line.
I have tried various invocations (there are probably 50 ways in which one can call LWP::UserAgent). with and without HTTP::Request::Common::DYNAMIC_FILE_UPLOAD, no luck..
