The package GSmartControl - http://pdb.finkproject.org/pdb/package.php/gsmartcontrol - doesn't have binaries for OS X 10.7 and 10.8.
*No packages* have binaries for 10.7, 10.8, or even 10.6.
This isn't a bug, it's a package request.
Thanks for the request.
I just added gmsartcontrol to the 10.7 tree and updated the version.
