Poppler need not be in the reposity, but it should be detected and
enabled, or available as a build option.
Such changes take time. We are likely to see simiilar issues for xetex and the
font libraries (especially if there are big changes in the way math
fonts are handled).
It takes time for new libraries to be ported to legacy platforms.
Some new libraries
may end up being discarded when some fundamental design flaw is
discovered or something better comes along.
Many packages already have configure options to select different
libraries -- xdvi can be built against 4 different X-toolkits (Xaw,
Motif 1.2, Motif 2.x, LessTif). The repository needs to support
transitional situations by providing multiple libraries and supporting
builds with either. It is messy, but necessary if you are going to
support legacy systems without stopping innovation and security
