If you look at the last part of the output, it displays the number of files, directories, paths installed and the number of executables installed.
To find the files installed
# pkgchk -v SUNWwgetu
/usr
/usr/sfw
/usr/sfw/bin
/usr/sfw/bin/wget
This will give details of the package files, directories, paths and executable installed. For wget the executable is in /usr/sfw/bin/
This should help!
