I need guile-json >= 4.2 because 4.2 provides guile-json-mapping

I modified PATH:

mbc@xps:~$ echo $PATH
/opt/gradle/gradle-4.8.1/bin:/home/mbc/bin:/gnu/profiles/base/bin:/usr/share/lintian/overrides:/usr/local/bin/guile:/home/mbc/.guix-profile/bin:/home/mbc/.nvm/versions/node/v12.16.3/bin:/usr/local/bin:/usr/bin:/bin:
mbc@xps:~$ export PATH=/home/mbc/.config/guix/current/bin/guix:$PATH
mbc@xps:~$ echo $PATH
/home/mbc/.config/guix/current/bin/guix:/opt/gradle/gradle-4.8.1/bin:/home/mbc/bin:/gnu/profiles/base/bin:/usr/share/lintian/overrides:/usr/local/bin/guile:/home/mbc/.guix-profile/bin:/home/mbc/.nvm/versions/node/v12.16.3/bin:/usr/local/bin:/usr/bin:/bin:


/home/mbc/.config/guix/current/bin/guix is first but:

mbc@xps:~$ hash guix
mbc@xps:~$ type guix
guix is hashed (/usr/local/bin/guix)
mbc@xps:~$

Thanks
