[OpenVZ]/dev/stdin や /dev/stdout が無い時の対処

VEコンテナでcpanつかってTemplate入れようとしたら、

cpan> install Template
Running install for module Template
Running make for A/AB/ABW/Template-Toolkit-2.22.tar.gz

なんでファイルが保存されていないんでしょ。とりあえず

/usr/bin/wget -O - "http://ftp.jaist.ac.jp/pub/CPAN/authors/id/A/AB/ABW/Template-Toolkit-2.22.tar.gz"  > /root/.cpan/sources/authors/id/A/AB/ABW/Template-Toolkit-2.22.tar

としたら、わかりました。

# /usr/bin/wget -O - "http://ftp.jaist.ac.jp/pub/CPAN/authors/id/A/AB/ABW/Template-Toolkit-2.22.tar.gz"  > /root/.cpan/sources/authors/id/A/AB/ABW/Template-Toolkit-2.22.tar

え？おいおい、これってもしかして・・・

# ls /dev/std*
ls: /dev/std*: No such file or directory

ありゃりゃ。。。/dev/stdin と /dev/stdout が無いんですね。
しょうがないんで、作りましょう。

# ln -s /proc/self/fd/0 /dev/stdin
# ln -s /proc/self/fd/1 /dev/stdout
# ln -s /proc/self/fd/2 /dev/stderr 

この辺を参考にしました。
