In principle yes (but you already know that) ...

but it requires the cairo plug-in to be build and activated. The first you 
can check yourself at File/Plug-ins in GUI mode. My guess is you switched 
off the cairo plug-in because libcairo_filter.so is missing in your list.

$ dia --version --verbose

can show you if Dia was built with cairo, e.g.

Dia version 0.97+git, compiled 14:24:19 Dec  1 2012

Compiler: MSC 1200
  with : threads cairo
Library versions (at compile time)
libxml  : 2.7.4 (2.7.4)
glib    : 2.33.4 (2.22.6)
pango   : 1.26.1 (1.26.1)
cairo   : 1.10.3 (1.10.3)
gtk+    : 2.24.11 (2.16.7)

I'm guessing the Fedora build of Dia is done with cairo support and the 
cairo version there is build with PDF support. But you should ask someone 
from Fedora to be sure.
So as I said above the most probable reason for the missing functionality 
is a deactivated cairo plug-in.
