[antoine druon <adruon@croquegel.com>]

I try to install mysql 3.23 on mandrake 9.0 but I have somme problems

first I have this problem /usr/share/rpm-helper/add-service: line 27: 
[: : integer expression expected a the end of install 
i saw for mandrake 9.1 a patch so i modified my add-service in rpm-
helper
but after that a the end of install i receive this 
message /usr/sbin/mysqld: Shutdown Complete
and impossible t start mysql with safe_mysqld
error message is : shell-init: could not get current directory:
