rst2man not found. You need the Docutils system to generate the manpages (preferably version >= 0.9; 0.8 and older are known to corrupt the arguments shown in some option descriptions). Alternatively you can use 'install-no-man' rule.

make[1]: ディレクトリ `/home/clothoid/app/mplayer2-build/mplayer' から出ます

と言われたから、

===
sudo aptitude install python-docutils
===

ってしたでござる。
