AFAIR there are two package formats, one is a one-file, and the other is a directory (one can convert to each other with the pkgtrans command).
The one-file package you install with
pkgadd -d /path/to/pkgfile
Your package seems to be the directory format, then it should be
pkgadd -d /Recovery/CloneDrivers SUNWpfbcf
Or just
pkgadd -d /Recovery/CloneDrivers
and it should ask for all (dir-format-)packages in there.
It then asked which package I wanted to install (and that all three is the default. Interesting, last year when we hammered out this process, I installed them from the CDROM and I don't recall having to do it this way.
