Versions make THAT much of a difference?

Hi,

SYSTEM H:

FreeBSD 5.5-STABLE

libwww-perl-5.805

SYSTEM S:

Trying to run :

POST -C root:password -u -U -s -S -e http://192.168.2.53:9090/axis-cgi/com/ptz.cgi

With the input of :

gotoserverpresetname=Camary+Due+East&camera=1

and then Ctrl-D to terminate after the new line.

Which is what I expect. I need the 204 in this case.
Weird but true.

Which ISN'T the right reply, it actually doesn't do what

Are the 2 versions of perl/LWP so diverse to cause that? Or
is there something deeper I should check?

Thanks, Tuc
