Whoever gave you this advice was wrong.  A symlink should already exist for 
perl:
# ls -lsa /usr/bin/perl
0 lrwxr-xr-x  1 root  wheel  24 Feb 20 12:23 /usr/bin/perl -> 
/usr/local/bin/perl5.8.8

Note that it doesn't point to /usr/local/bin/perl

Try running the perl-after-upgrade script:
# which perl-after-upgrade
/usr/local/bin/perl-after-upgrade
