Hum?  I do not know if I am doing correctly.  The packages
fakechroot-2.9-24.5.el6_1.1.x86_64.rpm and
fakechroot-libs-2.9-24.5.el6_1.1.x86_64.rpm are installed.  And I get
as regular user:

--8<---------------cut here---------------start------------->8---
$ export GUIX_EXECUTION_ENGINE=fakechroot
$ strace -f -s 500 -o logg ./bin/R
fakechroot: unsupported Guix execution engine; ignoring

However, as root, simply running ./bin/R returns:
