TRAC and PERL problems after upgrading from Hardy to Intrepid

[L.M.J]

Hi,

  I've just upgraded from Hardy 64 to Intrepid 64 and some of my
applications are not working anymore. First one :
 TRAC : "script not found or unable to stat: /usr/share/trac/cgi-bin"  
        trac.cgi doesn't not exist anymore on the system! I used to make my
Apache configuration like this:

        ScriptAlias /trac /usr/share/trac/cgi-bin/trac.cgi
        <Location "/trac">
            SetEnv TRAC_ENV "/home/trac"

            [...]
        </location>

 PERL : Can't locate Sys/SigAction.pm  Where I could find it?

 DEVMON : Can't locate BER.pm and
          Constant subroutine dm_config::SEEK_SET redefined at
/home/users/hobbit/application/server/ext/devmon/modules/dm_config.pm line
28
          

  Any ideas around to help on those issues?

   Thanks by advance!
