We know we're running from C shell in perl-homedir.csh, so be
explicit rather than letting local::lib guess.
If the SHELL environment variable is not set, perl -Mlocal::lib is
fooled into emitting bourne shell syntax (e.g., export FOO=bar)
instead of csh syntax (setenv FOO bar). This can be fatal to the
C shell possibly interrupting execution of a script before the
script has completed.
This (no SHELL variable set) can happen, for instance, when running a
cron job.
