Having some problem with instaweb

I am on Linux Mint 10 and I tried the following command:

$ git instaweb -d apache2 -p 1234 --start
Syntax error on line 1 of /mnt/storage/gurjeet/.git/gitweb/httpd.conf:
Invalid command 'server.document-root', perhaps misspelled or defined
by a module not included in the server configuration
Could not execute http daemon apache2 -f.


/mnt/storage/gurjeet/ is my $HOME.

I have tried commenting out that first line, but then the error
complains about line 2 'server.port = 1234'

Any help appreciated.

Thanks in advance.
