*cough* ... look again. 

'/var/tmp/otherdir/symdir/../datadir' => '/var/tmp/otherdir/datadir'
'/var/tmp/mydir/../datadir' => '/var/tmp/datadir'

You'll only ever get the same location if you are on the same directory level as the directory you symlink to. I suppose I should have made it easier to see by changing out /var/tmp/otherdir with just /tmp or some such.

Edit:

Here's the result if you make the last symlink just into /tmp: 

Finding a data path:

dirname($name):/tmp/../datadir
dirname(rel2abs($name)):/tmp/../datadir
dirname($0):/usr/local/bin/../datadir
dirname(rel2abs($0)):/usr/local/bin/../datadir
$FindBin::RealBin:/var/tmp/mydir/../datadir

Does that make it clearer for you?

Edit 2:

What good is readable if it doesn't work as well. And I don't see how dirname($script_qn) is less readable than $FindBin::RealBin.

Specifically, I find: 

dirname(rel2abs($0)) . "/../datadir"

[download]
less readable than 
$FindBin::RealBin . "/../datadir"

because of the nested parens.
