Well, newer versions of sort added the functionality you miss, citing
from the GNU coreutils manual [1]:
‘-h’
‘--human-numeric-sort’
‘--sort=human-numeric’
Sort numerically, as per the --numeric-sort option below, and in
addition handle IEC or SI suffixes like MiB, MB etc (Block size).
Note a mixture of IEC and SI suffixes is not supported and will be
flagged as an error. Also the numbers must be abbreviated
uniformly. I.E. values with different precisions like 6000K and 5M
will be sorted incorrectly.
This feature was introduced in GNU coreutils release 7.5, 2009-08-20 [2]
As the coreutils version in debian sid and squeeze (I couldn't verify
lenny) is newer, the following command will work:
du -sh |sort -hr
to have the largest files first. the sort(1) man page on debian
documents this behaviour.
So if it only takes one pipe and coreutils to implement the
functionality of dirsum, maybe it's not worth a package.
Cheers,
Mika
