Dear Guix,
When running R, it executes a wrapper script that relies on
@code{uname} to be available in PATH:
> R_HOME_DIR=/gnu/store/dz83xhn43qc2dpdrja8mhx78l7qffqvq-r-3.3.0/lib/R
> if test "${R_HOME_DIR}" =
> "/gnu/store/dz83xhn43qc2dpdrja8mhx78l7qffqvq-r-3.3.0/lib/R"; then
> case "linux-gnu" in
> linux*)
> run_arch=`uname -m`
> case "$run_arch" in
> x86_64|mips64|ppc64|powerpc64|sparc64|s390x)
> libnn=lib64
Running R in a pure, ad-hoc environment will therefore signal a warning
that it cannot execute "uname".
With the following patch, it no longer makes this assumption. Instead
it uses an absolute path to a uname binary from the Guix store.
