Restoring original perl

Hi all,
Can anyone help me here? I installed perl 5.6.1 on a RaQ3 (with cobalt
libs) but GUI fails - PostgreSQL failed. Must have done something wrong.

I have tried to roll back to the original version of perl by doing this

Re-made the hard link in /usr/bin by:
ln -f perl5.00503 perl

The /usr/lib/perl5 now contains
drwxr-xr-x   29 root     root         2048 Mar  7 12:24 5.00503
drwxr-xr-x    3 root     root         1024 Mar  7 12:24 man
drwxr-xr-x    3 root     root         1024 Mar  7 12:24 site_perl

These are the original sub dirs complete with the cobalt bits.

However on a reboot there are still no sites showing and postreSQL is
not running, even on a manual restart. It reports:
# /etc/rc.d/init.d/postgresql start
Setting up PostgreSQL: FATAL: StreamServerPort: bind() failed:
Permission denied
        Is another postmaster already running on that port?
        If not, remove socket node (/tmp/.s.PGSQL.5583) and retry.
/usr/bin/postmaster: cannot create UNIX stream port

Perl -v reports correctly as does Perl -V, c/w correct @INC paths
  @INC:
    /usr/lib/perl5/5.00503/i386-linux
    /usr/lib/perl5/5.00503
    /usr/lib/perl5/site_perl/5.005/i386-linux
    /usr/lib/perl5/site_perl/5.005

BTW mySQL also doesn't work so I have one db driven site down.

Is there any where else I need to look? Please?

Regards,
