See http://www.brorson.com/gEDA/SPICE/intro.html.

Note that schematics intended for pcb layout are generally difficult to simulate, and schematics intended for simulation are generally not suitable for pcb layout.

For simulation of a transistor, you will need to obtain a file of model parameters from some other source, typically the manufacturer. Most model parameter files are licensed under terms that prevent redistribution, so they cannot be distributed with gEDA.

These limitations are not specific to gEDA, but apply to other EDA packages as well.
