mysql-admin can't find mysql client

[Luigi Fonti]

I installed mysql-admin 1.0.19 on Linux RedHat, using rpm. It works, but it can't find the mysql client.
So, the 'tools' menu item doesn't appear, and the usefulness of the application vanishes.
mysql-admin is installed in /usr/bin and mysql client is there, too.

I tried to insert some item in /etc/my.cnf, like:

[client]
mysql=/usr/bin/mysql

but none of them worked.
Any suggestions ?
Thanks in advance
