Ormund, thank you for the info. For everyone's information here's
how I fixed the situation.
I used the software generated clock from the STK500's XT1 pin of the
PORTE/AUX header and manually jumped it to the ATmega's PB6/XTAL1
pin. Even with a 32.768 KHz crystal soldered to the XTAL1 net in my
target circuit, I was able to establish comms with avrdude. I had to
slow the bit clock and skip device verification like so::
$ avrdude -p atmega8 -P /dev/cu.KeySerial1 -c stk500v2 -V -B 100.0 -
F -t
avrdude> write lfuse 0 0xE4
avrdude> quit
And all was well again.

The ISP feature needs the oscillator running, avrdude cant do any
thing
without that. What you need is an external frequency source connected
to PB6(XTAL1), I once used an audo signal generator running at
10KHz and
"-B 1000".
