apache is configured with suexec
>Description:
We use <!--#include virtual="/lib/hello.shtml" --> in most of
our documents to include a footer and header line. If I do use such a
virtual include in document /~oetiker/demo.shtml (the included 
document is server parsed as well!) and subsequently try to use
<!--#exec cmd="demo.exec" --> (in /~oetiker/demo.shtm), suexec refuses to
do it, because it thinks that demo.exec is in the /lib/ directory.

this gives the following symptom in the cgi.log
[16:45:44 16-06-97]: command not in docroot (/usr/tardis/pub/www/lib/demo.exec)

if I remove the include virtual line things work fine ... also if I put the include 
virtual after the exec line or if the included file is NOT server parsed ...
>How-To-Repeat:
try the setup explained in above description
>Fix:
I did poke through mod_include.c but to no avail  ... :-(
