Hi, Ralf,

Thank you for the quick reply.

I have downloaded your adjustment, and it works fine with the original 
1.6.002 code base, and solves the setup problem.  At the same time, you 
may like to watch out for the other @dl() 's.  It appears that the 
default Fedora 12 environment does have enable_dl set to Off.

Best Regards,
CK
