D'oh!!  :-)

I'd like to think that under normal circumstances, I wouldn't miss 
something
like that --- but I guess between my lack of familiarity with gEDA 
terminology,
and the coincidence that "pcb tight" *sort of* makes sense... well....

I just tried, and the part I can't figure out is the last instruction 
that gsch2pcb
gives me.  I quote its output:

How exactly do I perform step 3?  The colon looks like vi syntax
(vi as in the text editor vi), but I try just typing and nothing happens.

Still, at that point, when I open with PCB, the LME footprint does not
show up  (not just the rat nets --- the LME itself is not showing up!!!)


So, I did the experiments as you suggested:   worked on the machine
with the distro packages (installed directly through the Ubuntu 
repositories).
gEDA version 1.6.2 20110115;  PCB Designer version 20110918.

Worked with the exact same files I had uploaded in the previous
message  (the ones you used and that worked on your side).  Quoting
from my previous message --- the following files:

This time, I used gsch2pcb  (command-line).

The footprint files are located at /usr/share/pcb/pcblib-newlib/generic/
The LME49811.sym file is located at  /home/carlos/tmp/symbols/
(the .gEDA/schemrc file contains the line:
(component-library "/home/carlos/tmp/symbols/" "User-defined") )


I did the following:  Created a directory PCBs and placed the .sch file
only.  Run gsch2pcb, then cp * step-1/  to copy all files generated into
that directory.  Then, open the .pcb file with PCB Designer, load nets,
disperse, optimize rats, then save.  Then, cp * step-2/

I enabled directory listings so that you can see all the files. Here's
the link:

http://www.mochima.com/tmp/PCBs/

Hope we can figure out where the problem is!   As you pointed out, a
bug in the PCB or sch2pcb programs sounds strange, since I tried on
several different machines, Ubuntu, CentOS, and with the distro versions
and also the versions installed from source (from the latest stable 
versions).

Again, thank you very much for all the effort and your comments so far!!!

Thanks,
Carlos
