pg_resetxlog command not found

I am doing some experimentation with a WAL archiving HA setup. I tried
turning to the pg_resetxlog command  after removing some corrupted
files and it is not installed using the ubuntu dapper 8.1 package. How
do I get this command installed, or is there some other way to repair
a database that is missing the pg_xlog directory files? I find it odd
that the pg_resetxlog command is just missing... I have postgres
installed from source on my laptop and it is there.

Thanks,
Matt
