No.  You also need to adjust pin numbers to match the symbol's pins to
the footprint's pins, one of our current sore spots.  That includes
such things as slotting.

For instance, a 2-in NAND could be (1,4,9,12), (2,5,10,13), (3,6,8,11)
for SN74ALVC00NSR, but 1,2,4 for NC7S00M5X in SOT23 (but the micropak
numbers Vcc as pin 6, not pin 5) or (1,7), (2,6), (3,5) for CD40107BE.

Plus, different vendors might number the pins on a SOT23-5
differently.  Some use 1,2,3,4,5; others use 1,2,3,4,6 (leaving '5'
for the missing pin).
