Currently, Ubuntu 8.04, MacOS 10.4.11. In the past, many other Linux  
and MacOS flavors since I started using gEDA about 6 years ago.

Synaptic (Ubuntu) and Fink (MacOSX) for the main stuff. In the past,  
built from source or used other package systems, depending on the  
availability of the version I needed.

I build my modified ngspice from source, naturally.

gschem, gattrib, gnetlist, tragesym, spicepp, ngspice.

Main workflows are:

gschem -> gnetlist -g calay	(a different contractor does PCB layout)
gschem -> gnetlist -g osmond	(the customer does PCB layout)
gschem -> gnetlist -g spice-sdb	(a different contractor does SPICE ->  
chip layout)

Also:

gschem -> gnetlist -g mathematica -> Mathematica	(symbolic circuit  
analysis)

Various simulation flows using ngspice, with spicepp as needed. This  
includes postlayout simulations of VLSI, as well as ordinary circuits  
from gschem.

Also gnetlist -g bom, and occasionally gnetlist -g drc2, although  
drc2 is very poor for mixed signal stuff.

I wrote the calay, osmond, and mathematica gnetlist back ends. Also a  
PH70 back end, but I think the last PH70 user has retired. I  
sometimes need to tinker with spicepp.pl. My ngspice is modified to  
support HSPICE noise models for some devices (have to get that  
flicker noise right).

Scientific instrumentation: imaging and particle detector support.  
Mixed signal: measurement chains, CCD clock drivers, high voltage  
generation, digital interfaces.  So far, my gEDA designs have been  
laboratory instruments, but I expect to get some into space in the  
next few years.
