# Bug report
### Bug description:
In the configure script, the only prerequisite for the `grp` module is currently the `getgrgid` function. Older versions of Android have this function, but they don't have the `getgrent` function, which the `grp` module uses unconditionally. This causes the build to fail as follows:
```
