So far, I think that the yum installed FC6 gnucap doesn't like the
spice netlist produced by gnetlist.  I say that because, when I
execute

$ gnucap try1.cir

I get messages that look like:

V1 in 0 PULSE(0 1 10ms 0 0 1s 2s)
   ^ ? need 2 more nodes
V1 in 0 PULSE(0 1 10ms 0 0 1s 2s)
        ^ ? what's this?
...

So I thought I would try compiling the latest development snapshot and
see if that imported my spice netlist better.

So, does that imply that the long term plan is that somebody would
write the appropriate backend for Gnucap?
