Control: retitle -1  r-cran-rstan: fails hard with 'Boost not found'
Control: tag -1 + patch

Thanks Michael and Dirk for the fix,

Just a quick comment for users who might be impacted before the stable
update:

So setting `boost_lib` at runtime to an arbitrary existing file or path
also prevents rstan from stopping, like with:

     rstan_options("boost_lib" = '.')

It is surprising that rstan never worked and we never noticed until this
week.  It is possible that we ship it merly because it is listed in the
Suggest field of the DESCRIPTION file of other R packages.  Often this
is because it is needed in the other package's unit tests, which makes
it strictly required for us, but sometimes it is only because some
optional support for it is provided by the other package, leading to
cases like this one.

Have a nice day,

Charles
