Comment:
With the `beta7`, using
```
checkdepends=${makedepends}
do_check() {
  ./sage -tp ${XBPS_MAKEJOBS} --all
}
```
I got the same errors as reported in https://github.com/void-linux/void-packages/pull/34030#issuecomment-968081092 , plus a few more ones, of the same nature (rounding errors). Do we have any issue or missing patch with `arb`?
