Paul Kukiel -
and what i'm interested in.

I was setting up a new server and compiling some apache conectors when I came across this error:

me@server.com: make
cd . && aclocal
/bin/sh: aclocal: command not found
make: *** [aclocal.m4] Error 127

Where does this come from and how do you fix it?

It's part of Automake . To fix it on Debian/Ubuntu:

apt-get install automake

and CentOs

yum install automake

Or you can download and set it up here.
