The error message from newlog(1) indicates that its first argument (the 
pathname of the log file) was unset. This is likely due to the perl(1) variable 
$log_file being unset in the ldmadmin(1) script (bin/ldmadmin). You can verify 
this by execute the command "ldmadmin config" and seeing what the value is for 
the log file.

If the value is unset, then please send me the output from the command "regutil 
/log".
