Neal Richardson commented on ARROW-7908:
----------------------------------------
It would indeed be nice not to have to set an env var, but this was a
concession made to CRAN policies. As you might guess from our rapidly going
from 0.16.0 to 0.16.0.1 to 0.16.0.2 last week, this wasn't the first choice.
I'm surprised however that the package doesn't at least build a limited version
that contains the {{install_arrow()}} function. If you wanted to help debug
that, could you try installing again without setting LIBARROW_DOWNLOAD and
instead setting ARROW_R_DEV=true to make it print more verbosely?

> It appears that the C++ code is not built. With arrow 0.16.0.1 things do work
> out, because it tries to build the C++ code from source. With arrow 0.16.0.2
> such is no longer the case. I could finish the installation by setting the
> environment variable LIBARROW_DOWNLOAD to 'true':
> {code:java}
> export LIBARROW_DOWNLOAD=true
> {code}
> That, apparently, triggers the build from source. I would have expected that
> I would not need to set this variable explicitly.
> I found that [between
> versions|https://github.com/apache/arrow/commit/660d0e7cbaa1cfb51498299d445636fdd6a58420],
> the default value of LIBARROW_DOWNLOAD has changed:
> {code:sh}
> - download_ok <- locally_installing && !env_is("LIBARROW_DOWNLOAD", "false")
> + download_ok <- env_is("LIBARROW_DOWNLOAD", "true")
> {code}
> In our environment, that variable was _not_ set, resulting (accidentally?) in
> download_ok being false and therefore the libraries not being installed and
> finally the resulting error above.
>
> I can't quite figure out the logic behind all this, but it would be nice if
> we'd be able to install the package without first having to set
> LIBARROW_DOWNLOAD.
