In the meantime I installed R and it seems to be functioning correctly.

I reran the tests with `make -k check' and the above test failed again,
but it was the only one.  I looked at the source of Sys.timezone and on
my system as currently configured (TZ is not set, there is no
/etc/timezone file) this function always returns NA, so the test cannot
succeed.  I built and configured my system following the Linux From
Scratch instructions, so (unless I made a mistake somewhere) it seems
this test is irrelevant for that system.  If this conclusion is correct,
maybe the test can be skipped if /etc/timezone does not exist, or at
least not error out.  Or does that mean my system is somehow
