There's not much difference between Tw 0.3 and 0.5 (at least if you use
a recent revision of 0.3), it's just a naming convention.
Re. poppler, I did note that you are using Fink and it only provides an
old version. I was just suggesting that that should be updated
eventually ;).

This only emphasizes the point that most likely there are issues with
poppler as provided by Fink (or as installed on your system).
Normally, Tw shouldn't touch any sources of poppler, it only requires
the header files and the libraries for linking. So it would probably be
a good idea to track down the reason the build process tries to build
(parts of) poppler. One wild guess would be that you don't have the qt4
backend for poppler (enabled by the --enable-poppler-qt4 configure
switch), or Tw doesn't pick it up properly, anyway.
