Fix bug in memory management

the call to the run function in libspec cannot be done
with unzip the OrderedDict values. It creates memory address
confusion and the program is killed by the os with a message:
"Operating system error: Cannot allocate memory
 Allocation would exceed memory limit"

To fix, we shall call the run function with each argument well specified
between the parentheses.
