Hi,
im from Germany and i had Problems too.
If you have Linux Debian install all the Packages are listet in the Howto.
apt-get install apache postgresql libdbi-perl libdbd-pg-perl libpg-perl libpdf-api2-perl
libclass-accessor-perl libarchive-zip-perl libtext-iconv-perl
libyaml-perl libtext-csv-perl libio-stringy-perl libtemplate-perl
It is important that you dind't use Subfolders. Untar all Files into Folder lx-erp in /var/www.
Then insert the following in your apache2.conf or vhost.conf
AddHandler cgi-script .pl
Alias /lx-erp/ /var/www/lx-erp/
<Directory /var/www/lx-erp>
Options ExecCGI Includes FollowSymlinks
</Directory>
<Directory /var/www/lx-erp/users>
Order Deny,Allow
Deny from All
</Directory>
For Example my lx-erp is installed on Debian in /var/www/lx-erp
My Website for lx-erp is located at /var/www/web4/web/lx-erp
The Problem is lx-erp can't find Perl when its installed in a Subdirectory.
But you can make a link for my Example it is In -s /var/www/lx-erp /var/www/web4/web/lx-erp
This works for me.
