well, I'll post the basics of one of my mt.cfg file below. The path to perl is correct as default so you don't need to edit that. And the other stuff is pretty self explnitory if you want to change things around.
## Movable Type configuration file [mt.cfg] ##
## ##
## This configuration file holds system-wide configuration ##
## settings that apply to *all* of the blogs in your Movable ##
## Type installation. ##
# Movable Type uses the CGIPath setting to construct links back to
# CGI scripts; for example, the MT tag <$MTCGIPath$> is substituted
# with the value of the CGIPath setting. You will need to change this
# value when you first install MT; instructions for doing so are in
# the Installation Instructions, in INSTALLING THE MOVABLE TYPE
# APPLICATION CODE, Step 3.
CGIPath http://www.myDomain.com/blog
# The filesystem path to the 'db' directory, where your MT database
# files are stored. You will probably need to change this when you
# first install MT; instructions for doing so are in the Installation
# Instructions, in INSTALLING THE MOVABLE TYPE APPLICATION CODE, Step 8.
# Consider using the MySQL configuration, below.
DataSource ./db
## The following options are commented out: to uncomment an ##
## option, remove the '#' at the beginning of the line. ##
## First, however, make sure that you understand the purpose ##
## of the configuration setting. ##
#
# Configuration for MySQL databases. Add the name of your database
# and the username that you have for logging in to that database
# below. The password needs to go in the file mt-db-pass.cgi.
#
ObjectDriver DBI::mysql
Database database_name
DBUser usEr
DBHost db.myDomain.com
#
# ThrottleSeconds is the minimum number of seconds between comments
# from a single IP address. Setting this to 0 will turn off the
# throttling feature, which may make you vulnerable to
# comment-flooding. The default is 20.
#
# ThrottleSeconds 20
#
# MT needs to have an email address, from which it can send notification
# emails. This defaults to your author address, but some spam filters
# will reject emails that are From: and To: the same address. If you
# have another address you can use it here.
#
EmailAddressMain me@mydomain.com
EmailVerificationSecret secreteWord
----- Now there's a bunch of lines that are all commented out untill this part-----
# When creating files and directories, Movable Type uses umask settings to
# control the permissions set on the files. The default settings for file
# creation (HTMLUmask, DBUmask, and UploadUmask) are 0111; for directory
# creation (DirUmask), the default is 0000. You should not change these
# settings unless you are running MT under cgiwrap or suexec, or some other
# scenario where the MT application runs as you; in addition, you should not
# change these settings unless you know what they mean, and what they do.
#
DBUmask 0022
HTMLUmask 0022
UploadUmask 0022
DirUmask 0022
#
---- And everything else in the file is default. ----
Should be pretty simple. Just read the lines where they explain what each variable is, and how to set it. Any line that starts with a # will be ignored by the program, so to "uncomment" something you just remove the #.
Hope this is helpful.
