Turns out that in my revamped TeX builder I was listing the .dvi or

.pdf output file as a sideeffect since it is listed as an output
file in the .fls file. This caused the message that there were two ways to
build the file.

In fixing it I have to exclude both the .dvi and .pdf target because some
test decks produce both... THat hsoudl rarely happen in practice but
It is better to handle that case.
