Broken at reinstall on CentOS7, possibly due to conflict with `sqlplus`

[Josh Marshall]

Good morning all,

For reasons I can’t divine, guix broke on my CentOS7 system and reinstalling 
does not fix the problem.  What might be going on here?

My $LD_LIBRARY_PATH after installation is the following

```

marshjo@ldg-jgm018:Downloads$ echo $LD_LIBRARY_PATH

/usr/lib:/use/lib64::/usr/lib/oracle/19.6/client64/lib:/usr/lib64/:/usr/lib/oracle/19.6/client64/lib

```



I suspect Oracle’s `sqlplus` is to blame, but the changes made by that install 
are effectively undocumented.
