Dear Greg,
I suggest:
gcc -Wall -O3 -o extgcd -I/usr/include/`gcc -print-multiarch`/ extgcd.c -L/usr/lib/ -lpari
or simply
gcc -Wall -O3 -o extgcd -I/usr/include/x86_64-linux-gnu/ extgcd.c -L/usr/lib/ -lpari
(but as a rule, avoid installing complex software in /usr/local/,
one day or another they will interfer with you distribution)
Cheers,
Bill.
