Case 1:
If the power pins are not connected to a wire or named wire stub they are not connected to a net.
(Even if the rest of the net has the correct name - the same as the pin)
This case is flagged by the design rule checker.
This case is flagged by the design rule checker.
Case 2:
In the case of the logic symbol '00' in the supplied 74TTL library, the power pins are only present on section 'A'.
If that section is not present for a particular package then the power pins are not implemented and do not appear in the netlist.
This case is NOT flagged by the design rule checker.
This case is NOT flagged by the design rule checker.
(Just put in section A with power pins visible and wired to solve it)
Hope this covers your case.

PS:
The 'HELP FILE' says:-
"Some component symbols, such as the 74 TTL library symbols, are automatically connected to power. To ensure the power is correctly connected, always use the same power names that are used in the library. For example, when using the 74 TTL library use the power names GND and VCC for 0v and 5v respectively."
- but I have not found this to be reliable.
> The power pins for one of the ICs (out of 49) are not in the net list.
> Other IC of the same type (oo) have the power pins listed. Any help?
