Btw, I agree w ethan: the syntax looks good to me. @ tells how to cast the reference; it doesn't dereference to get the first element.

But we need to see your ini file to be sure (I don't have the mtt code here w me to check it for sure).

How do perl -V differ between the two distros?

I can not reproduce the error on a SLES 10 machine.

Could you run MTT with the --debug option and send the output with the
line 75 perl error? That might help me determine which INI param is
responsible for the error.
