I've seen some tricky commands that act like that. You may have to spend some time experimenting on how to put the options into an array paired up. For instance:

my $command = "srver mgr";
my @options = ("-g $gateway", "-e $enterprise_server", etc, etc);

#then

system($command, @options);

The pairing needed can sometimes be needed in a specific order too. I had to spend an hour once, experimenting, because some of the options needed pairing, yet other options didn't. Drove me crazy. :-)
