PATCH: `- perl' instead of `- sh'

[Tanaka Akira <akr@jaist.ac.jp>]

On Solaris 7, `- sh -c ...' executes /etc/profile and $HOME/.profile
and doesn't execute shell commands provided by command line arguments.

I modified the test using perl.  Although there are hosts which perl
is not installed, it is less dangerous than sh, I think.
