R embeds an absolute path to the `which` executable in the sources for `Sys.which`. This gets ultimately stored as serialized byte code in some custom database format, which uses compression for entries. As a result, Spack cannot relocate `<prefix which>/bin/which` when installing from a build cache. The patch works around this by making R create a symlink to `which` in its own prefix, have the R sources call that, so that relocation works again. See r-devel/r-svn#151

Looks like CI for windows is broken due to timeouts when installing miktex

R hard-codes the path to the
whichexecutable inside bytecode, which isstored in a compressed format.
This makes it very hard to relocate R itself at a later stage, or update the
path to
whichif it ever moves on the system.This patch creates a symlink
rlib/R/library/base/R/which ->/path/to/bin/whichso it's easier to relocate R / which, as you can justmodify a symlink instead of dealing with
base.rdbandbase.rdxfiles.
