checkMD5sums(package, dir)
package | 
 the name of an installed package  | 
dir | 
 the path to the top-level directory of an installed package.  | 
The file ‘MD5’ which is created is in a format which can be
checked by md5sum -c MD5 if a suitable command-line version
of md5sum is available.  (For Windows, one is supplied in
the bundle at http://www.murdoch-sutherland.com/Rtools.)
If dir is missing, an installed package of name package
is searched for.
The private function tools:::.installMD5sums is used to create
MD5 files in the Windows build.
checkMD5sums returns a logical, NA if there is no
‘MD5’ file to be checked.
