I can't figure out why these errors occur:
```sh
$ cat masterdir/builddir/.xbps-gcovr/gcovr__do_check.log | grep 'not found'
/builddir/gcovr-4.2/doc/examples/example.sh: line 16: gcovr: command not found
/builddir/gcovr-4.2/doc/examples/example_branches.sh: line 8: gcovr: command not found
/builddir/gcovr-4.2/doc/examples/example_xml.sh: line 8: gcovr: command not found
```
