ftpmirror の古い方 1.21 が Perl-5.6.0 では動かない気がするので、 そう言えば 5.7.0 が出ている という話を見たので、開けて 見たが、UNSTABLE DEVELOPMENT release ということで、以前の 5.005_50 以降と同じなのですね。ftpmirror は 1.96 を動かし て見ることにした。

Sources for perl5 found in "/export/making/perl-5.7.0".
First let's make sure your kit is complete.  Checking...
*** WHOA THERE!!! ***

    This is an UNSTABLE DEVELOPMENT release.
    The version of this perl5 distribution is 7, that is, odd,
    (as opposed to even) and that signifies a development release.
    If you want a maintenance release, you want an even-numbered version.

    Do ***NOT*** install this into production use.
    Data corruption and crashes are possible.

    It is most seriously suggested that you do not continue any further
    unless you want to help in developing and debugging Perl.

Do you really want to continue? [n]  
Okay, bye.
