I have a /bin/readlink which does some of what you want.  It looks
like it's in package "debianutils", so I'm not sure if it's available
on the majority of systems.  Also, it doesn't do exactly the same, 
since it recursively follows symlinks - but I would guess that would
usually be what is wanted.

basename "`readlink "$1"`"

Alternatively you could reintroduce that Perl dependency that Michael
just helped you remove, and use Perl's readlink.  But I guess that
depends on whether you consider a bash script that make repeated calls
to Perl to still be a bash script :)
