(address . bug-guix@gnu.org)
I have bash configuration managed by guix home.
If I start a shell `guix shell ant`, and write `ant` followed by a
space and a tab, I get the following error:
```
bash: /gnu/store/mwj1bwipwf99bf82y0kpnv66ch7r1l25-profile/bin/complete-ant-cmd.pl: /usr/bin/perl: bad interpreter: No such file or directory
```
