Problems with hgwebdir

[Martin Marques]

I'm trying to get hgwebdir to work and I'm getting cgi errors. Following 
the info in the mercurial wiki I did this:

httpd.conf:

<VirtualHost hg.marquesminen.com.ar:80>
     ServerAdmin webmaster at marquesminen.com.ar
     DocumentRoot /var/www/hg/

     ScriptAliasMatch    ^/(.*)          /var/www/hg/hgwebdir.fcgi$1

     <Directory /var/www/hg/>
         Options ExecCGI FollowSymLinks
         AllowOverride None
     </Directory>

     ServerName hg.marquesminen.com.ar
     ErrorLog logs/hg.marquesminen.com.ar-error_log
     CustomLog logs/hg.marquesminen.com.ar-access_log combined
</VirtualHost>

The error log says:

[Fri Feb 01 18:01:31 2008] [warn] (104)Connection reset by peer: 
mod_fcgid: read data from fastcgi server error.
[Fri Feb 01 18:01:31 2008] [error] [client 192.168.0.5] Premature end of 
script headers: hgwebdir.fcgi

Any ideas?
