[ic] Install - Orders/Administration Not Functional

[Glenn McCalley]

IC 4.8.2 (new install)
FreeBSD 4.0
Apache 1.3.12
Perl 5.6.0
System load is negligible

Hi all, installing IC for the first time (many Minivend stores previously).
Installed the "foundation" store and all went well.  Store works, great!,
looks like this will be fun.
On the Admin side of things, the "Orders" button and the "Administration"
button both cause the ever-popular "Premature end of script headers" error.
Neither of the 2 IC error.log files (top level and catalog) have anything
illuminating, and the Apache error log says just the "Premature end...".

All other store and administrative functions seem OK - I've added items,
product categories, placed orders, etc., etc.  Suggestions?

TIA!
Glenn.
