--------------------------------------------+-------------------------------
 The `asciidoc` command is failing because it has `#!/opt/local/bin/python`
 hardcoded for the shebang line, and I don't have `python_select`
 installed. I fixed this by installing `python_select`, although I had to
 fix ''that'' up by adding an extra alternative, `python25-apple`, since
 I'm on Leopard (I'll report that bug separately).

 After that, `a2x` is still failing because it uses `readlink -f`, and the
 BSD `readlink` command works differently from the Linux one. I don't know
 if you want to report this upstream or just handle it with a MacPorts-
 specific patch file, which is why I'm reporting it here and not upstream.

 I temporarily fixed the `readlink` problem by defining a function called
 `readlink` at the top of the script which just does `echo "$2"`. After
 that, it works with no options. However,
 I've now found that the `--copy` option doesn't work, because it uses `cp
 -u`, which is another Linux-ism.
