Hervé,
"both" is a fairly recent addition and my guess would be that it has been
guarded specifically since it is the default and installing binaries only works
for the CRAN version. I didn't look at the new "both" code to see how it knows
that it's the CRAN version - there is really no special "CRAN" flag. At some
point we were guarding binary installs in general by checking the OS and R, but
it was fragile - you could be building using the same system as we do and yet
use a different compiler, so I think it's in general impossible unless we
introduce some extra identification of the binaries. So, yes, if you compile R
from sources yourself it is not guaranteed to be compatible with CRAN package
binaries. Those are only built and tested with the CRAN R binary.
Cheers,
Simon
