We are trying to port TeXworks as a package on Fink (
http://www.finkproject.org/). According to Fink packaging policy, for the
installing the dependencies of the application we are trying to port, we
must use packages already on Fink. The versions we mentioned for poppler and
other dependencies are the latest ones currently available on Fink. Hence,
moving to a newer version of poppler ( Hence, TW) is not feasible at the
moment.

As we mentioned above, poppler must be installed using the Fink package
which has already been built according to Fink packaging policy. It could be
possible that .moc files created in the process are for some reason not
available after installation. We shall try to verify the same by installing
poppler from source.
