Use component-library-search as in:

$ grep component-library-search ~/.gEDA/gafrc
(component-library-search "/Net/cvs/cvs.gedasymbols.org/www/user" "cvs")
(component-library-search (build-path (getenv "HOME") "git/openhw/share/gschem") "lcl")

Hope that helps.

It was added Dec 23 2011 so probably not many know about it (not even 
me till I searched for a previous version). And the documentation don't
seem to been updated with this new feature. At the bottom of:

 http://wiki.geda-project.org/geda:gschem_ug:config

the text describes another (previous) component-library-search that does
not do the same thing.

Anyone (please) is welcome to file a bug or provide a documentation
patch for this.

> and that names collide.
...

Yes, that is a major pain. 

Look at http://wiki.geda-project.org/geda:file_format_spec#component
It says that it is only the basename (i.e. the file name without any 
directory parts in it) of a file. For example:

C 18600 19900 1 0 0 7400-1.sym

So if you have sym files from multiple sources, this situation is 
unmanaged, and in my opinion this is a deficiency of the file format.

In may 2011 when I did the c version of an enhanced component-library-search
(the scm version is mainly done by Luigi Salvatore), I found
(http://archives.seul.org/geda/user/May-2011/msg00646.html):

<<
 There is 71 duplicate and 6 triplicate symbols names in the cvs.
 One of the triplicate is triac-1.sym, and searching for triac in
 the browser gives me five alternatives:

 dj_delorie/symbols/nvsemis
  triac-1.sym
 dj_delorie/symbols
  triac-1.sym
 levente_kovacs/symbols
  triac-1.sym
 werner_hoch/symbols/sf
  triac-2.sym
 Basic devices
  triac-1.sym
>>

Also:

<<
 Using the basename of a file to find it opens up for ambiguity.

 Consider a schematic containg components a.sym and b.sym,
 and two libraries with

 path1/ a.sym b.sym
 path2/ a.sym b.sym

 and suppose we want path1/a.sym and path2/b.sym.
>>

We really do need something more than the basename to resolve which 
symbol we want.

I propose that we add something after the basename to resolve the 
conflict. E.g. I want diode.sym, which sym file is then choosen?

$ locate /diode.sym
/Net/cvs/cvs.gedasymbols.org/www/user/kai_martin_knaak/essential/symbols/discrete/diode.sym
/Net/cvs/cvs.gedasymbols.org/www/user/kai_martin_knaak/symbols/discrete/diodes/diode.sym
/Net/cvs/cvs.gedasymbols.org/www/user/max_christian_pohle/symbols/diode.sym
/home/karl/git/openhw/share/gschem/diode.sym

One could possibly solve that by stating that an attribute should match:

 C 18600 19900 1 0 0 diode.sym "author=Karl Hammar"

as in:

 $ grep author diode.sym
 author=Karl Hammar

or that the path to the file should match:

 C 18600 19900 1 0 0 diode.sym "path contain essential"

Any thoughts?
