[Diy_efi] help with Eagle PCB software

Here are the warnings I'm getting:
 
WARNING: Sheet 1/1: POWER Pin U1 VSS(PIN8) connected to GND
WARNING: Sheet 1/1: POWER Pin U1 VSS(PIN19) connected to GND
WARNING: Sheet 1/1: POWER Pin U1 VDD connected to VCC
WARNING: Sheet 1/1: POWER Pin U2 VSSA connected to GND
WARNING: Sheet 1/1: POWER Pin U2 VDD connected to VCC
WARNING: Sheet 1/1: NC Pin U2 NC1 connected to GND
WARNING: Sheet 1/1: NC Pin U2 NC3 connected to GND
WARNING: Sheet 1/1: NC Pin U2 NC4 connected to GND
WARNING: Sheet 1/1: POWER Pin U2 VSSD connected to GND
WARNING: Sheet 1/1: POWER Pin U2 PSEN connected to V+
WARNING: Sheet 1/1: NC Pin U2 NC5 connected to GND
WARNING: Sheet 1/1: POWER Pin U2 VBATT connected to V+
WARNING: Sheet 1/1: NC Pin U2 NC2 connected to GND
WARNING: Sheet 1/1: NC Pin U2 NC7 connected to GND

WARNING: Sheet 1/1: NC Pin U2 NC8 connected to GND
WARNING: Sheet 1/1: POWER Pin IC1 IN connected to V+
WARNING: Sheet 1/1: POWER Pin IC1 OUT connected to VCC
 
The ones that say pin XXX connected to V+ are what concern me.  I originally added V+ from the supply1 library and renamed some of them to VBATT and some to VIGN.  That gave me errors.  I deleted them, and added new components VBATT and VIGN to the supply1 library.  Added them to the schematic but it's still referring to V+.
 
Can someone give me a little more detail on how to work with supply pins?  How do I create VIGN and VBATT, and then add them to my schematic?
 
thanks,

If it fails an Electrical Rule Check, then double-check the
connections on the power pins, including those on devices with
designated power supply.

If you've used standard pads for connectors and not run traces
between them, then it's usually a matter of not connecting to a
signal on the schematic, or using an inappropriate name.

Select the "show" mode for the pointer on the schematic and
double-click on the power traces. The "pins" on the connected
devices and the corresponding net will be highlighted. If the ones
you expect to be highlighted aren't, they're not really connected.

The online help for ERC explains what it checks to some greater
detail. The error report isn't quite as helpful as it could be.
