Log Message:
Update security/p5-Digest-MD5 to 2.27.  Changes from version 2.24 include:

   Don't assume PerlIO_read() works like fread() even though
   it was documented like that for perl 5.6.  It returns negative
   on read failure.

   The $md5->addfile method now croaks if it discovers
   errors on the handle after reading from it.  This should
   make it more difficult to end up with the wrong digest
   just because you are to lazy to check the error status
   on your file handles after reading from them.

   Improved documentation.
