IF php finds an error it outputs something, usually a header and some text.
"Parse error: parse error in
/var/www/groupware.gardeneden.net/header.inc.php on line 38"
in this case.

that's line 38.
Warning: Cannot add header information - headers already sent by (output
started at /var/www/groupware.gardeneden.net/header.inc.php:38) in
/var/www/groupware.gardeneden.net/setup/index.php on line 24

do you think it's a coincident that it says "output started at
/var/www/groupware.gardeneden.net/header.inc.php:38"?

since the error was on 38, the output will start on 38 as well.

re-read, re-think and realize ;o)
