Option 1: use combination of unlang (to select accounting packet type)
and rlm_exec (see modules/echo for example). This way the perl script
will be treated just like any other executable (not using rlm_perl, I
know, but some people might find it simpler)

Option 2: use rlm_perl, read modules/perl. You need to know about
creating functions in perl. Some snippet from that file:
...
        #  The following hashes are given to the module and
        #  filled with value-pairs (Attribute names and values)
        #
        #  %RAD_CHECK           Check items
        #  %RAD_REQUEST         Attributes from the request
        #  %RAD_REPLY           Attributes for the reply
...
        #
        #  List of functions in the module to call.
        #  Uncomment and change if you want to use function
        #  names other than the defaults.
        #
        #func_authenticate = authenticate
        #func_authorize = authorize
        #func_preacct = preacct
        #func_accounting = accounting
...

The function assigned to func_accounting should then be able to
differentiate whether it's an accounting stop or interim-update by
looking at values on %RAD_REQUEST.
