Cエクステンションビルドに必要なpython.hなんかがないとお怒りのご様子ですね。
とりあえず必要そうなファイルを入れてみる。
# yum -y install gcc gcc-c++ kernel-devel python-devel
パッケージ入れた後、pip install を実行してパッケージが無事に入りました。
# pip list | grep psutil
psutil (5.2.0)
minimalでOS入れるとこういう細々したのが入ってなくて邪魔くさいですね……
とりあえずインストールに失敗した時は「error:」のある行をバーっと見てちまちまパッケージ入れるしかないっすね。
 # python --version ){kind=link}
