[R-pkg-team] Bug#1108078: r-cran-rstan: fails hard with 'Boost not found'

[Graham Inggs]

Hi Everyone

I would have hoped that r-cran-rstan's autopkgtests would have caught
this, but looking at the output of a recent test in trixie [1] below,
it seems the autopkgtest is missing a dependency on at least gcc, and
despite the large WARNING, the test is not considered a FAIL.

Regards
Graham

64s rstan version 2.32.7 (Stan version 2.32.2)
64s
64s For execution on a local, multicore CPU with excess RAM we recommend calling
64s options(mc.cores = parallel::detectCores()).
64s To avoid recompilation of unchanged Stan programs, we recommend calling
64s rstan_options(auto_write = TRUE)
64s For within-chain threading using `reduce_sum()` or `map_rect()`
Stan functions,
64s change `threads_per_chain` option:
64s rstan_options(threads_per_chain = 1)
