Fan Speed Control Script on 6.2+, problem installing pwmconfig

[partytimexcellent]

I'm using a Buffalo TeraStation that has a single case fan. Stock, the fan runs at full speed all the time. I initially installed 6.1.7 and was able to follow a couple of guides to get control over the fan, which involved installing IPKG to add bash, perl, lm-sensors, & pwmconfig.

 

Now I'm trying 6.2.2 and am unable to install IPKG because it's trying to install to /opt/bin/, and these folders seem to no longer be present. Is anyone here say enough to walk me through how to get IPKG, or some other method of installing lm-sensors and pwmconfig? Thanks
