Yes.  Not all build dependencies are there (partly because of licensing; ECW,
MrSID, FileGDB...) and as poppler is only used by GDAL, I didn't package it.
It's just linked into GDAL.

Ah, ok.  I didn't check.

That, and it also doesn't make a lot of send to me - unless the aim is to
provide libraries to third parties.

Sure.  We also ship the libraries needed to build packages for OSGeo4W on top
of dependencies in OSGeo4W.  Just not libraries, that aren't used in OSGeo4W
otherwise.  But that's no strict rule either.  E.g. we also ship QGIS libraries
and headers - although we currently don't have any packaged C++ plugins for
QGIS in OSGeo4W.

Yes, of course.  That's how I understood it.

That was more about me volunteering. ;)
