While I'm fully ok with a script doing the integration (that can very 
easily be invoked
by a wrapper providing a button aka IDE) I want to second this and 
describe how I think
the internal working may be influenced:
*) as it is deterministic, that attachment of a footprint with 
non-matching pin/pad-numbers
  to a given symbol - that is last seen by the converter if I 
understand it right - will cause trouble,
  a clean converter will reject such combinations and list the
  - ref-des
  - symbol(-file)
  - path the symbol was found in
  - footprint(-file)
  - path the footprint was found in
 of the offending aggregate per default.

If this causes laughter in some corners, forgive me, I'm not aware of 
all the flags the converters
might have and "man gsch2pcb" produces nothing on my system.

While I see fit and like scripts my fight with gEDA the last 2 weeks can 
by no means
be described as productive - I used Eagle before, but as this was hobby 
and would
be illegal with what I (try to) do now. Believe me, I fully understand 
the difference
between footprints and its instances on a board and am able to think of 
things like
SQL-databases providing a clear, yet flexible mapping between
  - symbols
  - physical packages
  - vendor part numbers
  - manufacturing process
  - board characteristics (1 ounce, 2 ounce, FR2, FR4, ...)
  - HF electrical charateristics, thermal,...

It would however be very convenient for me, if I can be sure, that 
missing pins in
the ratsnest tool are not due to an incompatible choice of footprint for 
a symbol.
