mod_proctitle on linux

Приветствую, господа!

Попробовал поставить mod_proctitle (ftp://ftp.springdaemons.com/soft/mod_proctitle-0.3.tar.bz2) на CentOS 5.2

После ./configure && ./make получил

# make

make  all-recursive

make[1]: Entering directory `/root/src/mod_proctitle-0.3'

Making all in src

Подскажите, пожалуйста, как его скомпилить?
