Hi Girvin,

it may sometimes be necessary to remove ~/.cache/guile/, as well.

That's weird.  "Loaded RC file [/home/gherr/.gEDA/gafrc]" only shows up 
once in the gschem log you attached, but the "Library name [...] already 
in use." messages seem to indicate it was read twice.

These are the symbol "name.sym" from the first time the library was 
loaded, and the symbol "name.sym" from the second time the library was 
loaded; i.e., it's the same symbol.

BTW, you can include a whole hierarchy of library directories using 
"component-library-search".

The last 34 "More than one component found ..." lines are duplicated, as 
are the 37 lines before that.  I'm not sure what's going on here, but 
maybe you can figure out by looking at the symbol names?

Only in the first group:
   E-jumper-3.sym
   Q-2N2222-1.sym
   RP-sip10c-1.sym
   U-74x138-1.sym
   U-74x14-1.sym
   U-74x164-1.sym
   U-74x165-1.sym
   U-arduino_pro_mini-1.sym
   generic-power.sym
   grh-D-2.sym

Only in the second group:
   DS-st1113-1.sym
   S-Grayhill-87BB3-201-1.sym
   TB-Screw_1x12-1.sym
   U-74x05-1.sym
   U-74x240-4.sym
   U-74x244-8.sym
   U-74x374-1.sym
   grh-Dc-2.sym

In both groups:
   DS-led-1.sym
   R-RC07-1.sym
   U-74x175-1.sym
   continuation-1.sym
   ground_d-1.sym

In your gafrc file, it says:

;  03/21/18 [...]
;   Found the problem! I copied the old gafrc to my home directory
;   and gschem was also looking there as well as the usual dirs.
;   Thus the duplicates.

Maybe that's a useful clue?

> What could cause gschem to read files twice and how do I fix it?

I'll have to investigate this further.  I you find out anything useful, 
please let me know.
