for some reason you can not chain multiple commands inside an 'open' sub
routine call ... the second 'open' call is the one you're interested in.

this is actually the second script I've had to fix up. The first was the
script that inserted stuff into the fulcrum search engine. So if things
start magically not working in perl check out your scripts. This is only
apparent on spider and it only started happening in the last six weeks or
so. I installed the current installation of perl in November, so it could
have been broken since back then. The only thing really different is that
I've compiled most of the stuff on spider with SparcWorks 5.0 and
everything was definately working before then...
