The problem is that there's no generic way for hooking gethostname(3)
into a Perl script.
I rather consider this an omission of Perl. Anyway, the simple
solution:
------8<-----8<-----8<-----8<-----8<-----
package gethostname;
sub gethostname {
return `hostname`;
}
1;
------8<-----8<-----8<-----8<-----8<-----
should always do the trick. My concern was to avoid the overhead from
the additional process, and the fact that i don't like to call
unneeded external programs at all in setuid scripts.

Never trust an operating system you don't have sources for. ;-)
