Thanks! I copied gearmand into ~/dw/bin and attempted to do all this:

$ perl Makefile.PL
$ make
$ make test
$ make install

But I got this:

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
ERROR: Can't create '/usr/local/bin'
Do not have write permissions on '/usr/local/bin'
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

so I had a look and there is a /usr/local/bin/gearmand, but clearly this isn't the *right* gearmand for it to look at, I want it to look at the one in ~/dw/bin instead..
