apache web server problem

[Stephen Brenner]

Everything is working fine out of the root web directories,
but when I try to run out of /home/*/public_html I get the
following in the error log: "premature end of script headers".
I've always associated that error with a cgi script attempting
to write output prior to performing a "print $cgi->header('text/html');"

My httpd.conf includes a section for /home/*/public_html and it does
allow execcgi.

Any idea what's missing here?

Thanks,

Steve
