 >Description:
 
 Running the "pkg_info -g" command can sometimes improperly result in
 pkg_info reporting MD5 checksum mismatches for files that have simply
 been modified, either by the user or by some other port or package
 installation process, since the time when the file(s) in question
 were first installed.  This is entirely inappropriate as it can cause
 the system administrator to worry and fret that some file or files
 that were installed as parts of ports or packages have gotten corrupted
 somehow, when in fact the files in question, which may be locally con-
 figurable config files have merely been locally configured.
 
 More information on this problem can be found here:

 >How-To-Repeat:
 
 portinstall p5-XML-SAX
 portinstall p5-XML-LibXML
 pkg_info -g 'p5-XML-SAX*'
 
 (The second portinstall invocation above will result in the file named
 /usr/local/lib/perl5/site_perl/5.14.2/XML/SAX/ParserDetails.ini which was
 already installed as part of the p5-XML-SAX install to be diddled.  There
 after, pkg_info -g 'p5-XML-SAX*' will claim that the file is failing its
 MD5 checksum check.  This is arguably true, but is also entirely superfluous,
 pointless, and unnerving for the typical sysadmin.)
 
 >Fix:
 
 Left as an exercise for the reader.
  
 But seriously folks, a proper fix should be fairly trivial.  I will cook
 up patches, if requested.
