No, more like:
pseudo-device bpfilter 8
where the '8' can be any number - it's the maximum number of tcpdump (or
similar) programs you wish to run simultaneously.

Solutions:
a) Add the current directory (".") to your path. Not recommended in multi-user
environments, as it is a security risk
b) You can run executables from your current directory explicitly - eg.
./MAKEDEV
You certainly don't need to keep changing the path.
