Hi all, I can't even get it sintalled correctly

I've installed Perl ----------> no erros occured

I've installed apache web server -----------> no errors occured

MySQL -----------> no errors either, as I remember

but with Koha using installer.pl

Checked for missing modules: done all instaled

but errors with Z3950 client, but it's not really necessary..

Y downloaded yaz .rpm, I've sintalled it, but when doing a

perl -MCPAN -e "install Net::Z3950"'

it says that maybe it's not installed.

Another thing, I have the same problem of another guy I don't remember who:

Creating the MySQL database for Koha...

# [apache is running, and mysql daemon also, and i've set up a that password allready ]#

Couldn't connect to the MySQL server for the reason given above. This is a serious problem, the database will not get installed.

Press <ENTER> to continue:
