poppler: Add library dependencies

[someuser12]

Poppler and libpoppler actually depend on several dependencies that were not mentioned in the Portfile (can be checked e.g. with otool -L /opt/local/lib/libpoppler.19.dylib). I attach a new version of the Portfile that adds explicit dependencies to tiff, libpng, bzip2, zlib, fontconfig, freetype, expat. This is probably not exhaustive, but, hopefully, better than nothing.

Incidentally, the new Portfile updates to version 0.18.3 that was released on January, 15th, 2012.

The use of such explicit dependencies can be to find which ports one has to rebuild after an upgrade. For instance, after an upgrade of tiff, port dependents tiff would show the extensive list of ports that depend on tiff and that one should rebuild. Presently, poppler is not listed, so that the user discovers that he/she should have rebuilt poppler only at the time he/she fails to launch e.g. pdflatex.

Thank you for your consideration!

Please attach a universal diff of the Portfile so we can see the changes you made.

[someuser12]

Sorry. Here it is.

[mf2k (Frank Schima)]

Thanks. I meant unified diff of course. Also if you append ".diff" to the name, as I have just done, then Trac even colorizes it.

patch to Portfile 0.18.2

Meanwhile, the poppler port has been updated to version 0.18.4. I updated my Portfile proposal and patch-Portfile accordingly (but not patch-Portfile.diff since I dont't own it).

The fontconfig dependency was already added in r90941.

In #32793 the gtk2 dependency was deleted, which also had the effect of deleting the indirect glib2 dependency, which is needed to build the poppler-glib library, so this dependency has to be added again.
