Dale,

You've only shown that /sbin isn't in your path.
As a plain user:

$ dd if=/dev/zero of=./pkg.img bs=1024 count=100
100+0 records in
100+0 records out

$ /sbin/mke2fs ./pkg.img
mke2fs 1.18, 11-Nov-1999 for EXT2 FS 0.5b, 95/08/09
./pkg.img is not a block special device.
Proceed anyway? (y,n) y
