I see. Basically, what it's saying is that you can't md5sum a directory.
Here's what I would do. Once you change directory to $SRC (cd $SRC):
  • Check if each file is a regular file or a directory.
  • If it's a regular file, continue with the current for loop.
  • If it's a directory, change to this directory and then you'll have to write another for loop to perform the same test with each file inside. Once done, go to its parent directory and resume the main loop.
Writing a for loop with a couple of conditionals is not that difficult. If you need help to know how to determine if a certain file (the way Unix or Linux sees it) is a regular file, let us know.

lcf

LCF(1)							      Debian GNU/Linux manual							    LCF(1)

NAME

       lcf - Determine which of the historical versions of a config is installed

SYNOPSIS

       lcf [options] <Destination File Name> <Historical MD5SUM source directory>

DESCRIPTION

       This script, given a destination file name, and a directory containing md5sums of historical versions of the file, attempts to determine if
       the installed version corresponds to a historical version. lcf uses the same algorithm that ucf uses, and should exhibit  the  same  behav-
       iour.

       The  source  directory  is  the place where historical md5sums are expected to live. Specifically, the historical md5sums are looked for in
       either the file ${filename}.md5sum, or the subdirectory ${filename}.md5sum.d/

OPTIONS

       -h, --help
	      Print a short usage message

       -n, --no-action
	      Dry run. Print the actions that would be taken if the script is invoked, but take no action.

       -d [n], --debug [n]
	      Set the debug level to the (optional) level n (n defaults to 1). This turns on copious debugging information.

       -v,  --verbose
	      Make the script be very verbose about setting internal variables.

FILES

       /var/lib/ucf/hashfile, /etc/ucf.conf

SEE ALSO

       ucf(1) ucf.conf(5).

BUGS

       There are no bugs.  Any resemblance thereof is delirium. Really.
