[racket] PLaneT: Broken table of contents links in scribble

Hey there!

After struggling to document my first planet package, I find that
either Scribble or PLaneT is incorrectly rendering the links in
my package documentation's table of contents. Is this a bug or am
I doing something wrong?

To see the issue, visit:
http://planet.plt-scheme.org/package-source/gcr/openal.plt/1/5/planet-docs/openal/index.html
and click any of the links on the table of contents. For
instance, clicking on the "Constants" section takes me to:
http://planet.plt-scheme.org/#(part._.Constants)

These docs are built correctly on my local documentation copy
(the one that "raco docs" takes me to).

Unfortunately, mine isn't the only package with this problem. For
instance, click the "API" link here:
http://planet.plt-scheme.org/package-source/ebellani/cyclic-redundancy-check.plt/1/2/planet-docs/crc/index.html

Or click any of the links on this table of contents:
http://planet.plt-scheme.org/package-source/williams/diff.plt/1/0/planet-docs/diff/index.html

Interestingly, this package seems to work correctly -- is that
because it's multi-page?

P.S. Yes, I know (planet clements/rsound) is better, but I wanted
to practice with something a bit lower level. Plus, it's nice to
be able to stream raw sound data from a port instead of loading
it all into memory. ;) I don't mean to step on toes!
