Does this explanation make sense?
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=22402#37

If so, then you should read the warnings and investigate which files are
colliding. Some, like the hicolor icon-theme.cache, seem harmless to me,
although I welcome a second opinion.

I don't know about this one. Files the .la extension are used by libtool
but I don't have enough experience with libtool or know enough about
libatomic to know if this is going to be a problem.

Yes this is a continuation of my previous question. Thanks for response. I didn't

show the complete output. But I tried to show there are 13987 LINES in the error

messages. It's not so much the particular cases, it's Why is this happening at all?

Did I do smething wrong or is this software error? ANd, what is the proper procedure to

removal of one of the options?

Is it something like:  

guix package -r /gnu/store/wfvxxpdhnzd59vkad1zasm4f858giv9a-gcj-4.9.3/lib/libatomic.la

or is it
guix package -r /gnu/store/wfvxxpdhnzd59vkad1zasm4f858giv9a-gcj-4.9.3

or is it
guix package -r / gcj

And can it be done globally?

THere must be something I'm not doing correctly.
