There are a couple of open source packages, I use (and develop)
gEDA/PCB. When people complain about the limited library, I point out
that no matter how big the library, you're going to end up making your
own symbols and footprints, because new parts come on the market. So
you should not just look at what's ∗in∗ the library, but how easy is it
to add to it?
In PCB, for example, you can make new footprints right in pcb, even
while laying out your board. Symbol creation is done right in the
schematic editor. In both cases, the files are documented text files,
you can create them with a text editor, and there are scripts available
for automating it (I use djboxsym for 90% of my symbols). Heck, one
user created a programming language specifically designed to create
footprints.
Some web-based symbol/footprint tools for gEDA/PCB:
http://vivara.net/cgi-bin/djboxsym.cgi - online box-symbol generator
http://www.gedasymbols.org/user/dj_delorie/tools/dilpad.html - online
DIP footprint generator
http://www.gedasymbols.org/ - site for community-provided stuff
And a brief tutorial which includes making a footprint in PCB:

to ask questions at #geda on OFTC.net, where I hang out most of the time.
