I am attempting to re-build maildrop with the latest production version, 2.0.1. I know the switches I used...but when I hit the "make" command it falls apart starting with:

filelock.o(.text+0x68): In function `FileLock::do_filelock(int)': /usr/src/maildrop-2.0.1/maildrop/filelock.C:56: undefined reference to `ll_lockfd' maildir.o(.text+0x323): In function `Maildir::MaildirSave()': /usr/src/maildrop-2.0.1/maildrop/maildir.C:200: undefined reference to `libmail_kwhInit'

- snip -

recipenode.o(.text+0x1366):/usr/src/maildrop-2.0.1/maildrop/recipenode.C:1483: u ndefined reference to `rfc822a_free' recipenode.o(.text+0x136e):/usr/src/maildrop-2.0.1/maildrop/recipenode.C:1484: u ndefined reference to `rfc822t_free' collect2: ld returned 1 exit status make[2]: *** [maildrop] Error 1 make[2]: Leaving directory `/usr/src/maildrop-2.0.1/maildrop' make[1]: *** [all] Error 2 make[1]: Leaving directory `/usr/src/maildrop-2.0.1/maildrop' make: *** [all-recursive] Error 1

What did I forget to include ? Do I need more modules for 2.0.1 than with 1.8.1 or 2.0.0 ?
