guix pull: computing Guix derivation takes forever

[akib via]

I've just installed Guix on a partition of my new HDD.  After the 
installation I logged in to my user account on a Linux console and 
executed 'guix pull'.  After that it pulled the repository and computed 
Guix derivation, but stuck while updating substitutes.  So I thought 
something is wrong and restarted the command.  Now the pull operation 
always stucks while computing Guix derivation.  There is no sign of 
activity according to top.

Is this maybe related to the CC'd bug?
There the freeze happens later, during the building phase for
packages-base, but it seems like the symtoms are the same.
Does this happen every time you try?
Could you get a backtrace with GDB?
I think the incantation was:
set logging on
thread apply all backtrace
quit

And then the output should be gdb.txt.
