First of all it is IMHO no good idea at all to call Perl scripts with system
in an usertag. Put the functionality of the script into a module and
include this with Interchange, or if the script is too large and or
seldom used, allow it to be called via CGI or SOAP. Additionally I doubt
that a Perl scripts needs to be use mysqladmin instead of SQL commands.
