 I ran into exactly the same problem today, while trying to install
 graphviz (after port selfupdate and upgrading outdated ports).

 I took a look at /Library/Receipts, which included these (all from the
 same time on April 30, 2009):
 {{{
 swi-prolog-5.6.64.pkg
 zlib-1.2.3.pkg
 readline-5.2.012.pkg
 ncursesw-5.7.pkg
 ncurses-5.7.pkg
 libmcrypt-2.5.8.pkg
 jpeg-6b.pkg
 gmp-4.2.4.pkg
 expat-2.0.1.pkg
 }}}
 I think that I used the package installer available at [http://www.swi-
 prolog.org/download/stable]. It states: "SWI-Prolog/XPCE 5.8.3 for MacOSX
 10.5 (Leopard) on intel
 Installer with binaries created using Macports. Installs
 /opt/local/bin/swipl."

 When I today ran port install -f graphviz, I noticed that it reported
 moving expat. zlib, ncursesw, ncurses and jpeg files - all of which were
 installed by SWI-Prolog... I'm not a developer and I don't know anything
 about the relationship between package installers and MacPorts, but it
 might be worht taking a close look at the cited SWI-Prolog package
 installer.

 Hope this helps.
