make all exits with error 1

[Oliver Demetz - Hardware-XPress.de]

Hi!
I'm having weird problems compiling cyrus-imap-2.1.15 on my debian
machine.
SASL works quiet fine, SMTP AUTH with Postfix, too.
My configure-params were as follows:
# ./configure --prefix=/usr --with-cyrus-user=cyrus --with-cyrus-group=mail --with-auth=unix --with-sasl=/usr/local/lib/sasl2 --libdir=/usr/lib

But I get following negative lines in its output:
checking for makedepend... /root/src/cyrus-imapd-2.1.15/tools/not-mkdep

Then,

In the whole make-output, /usr/local/... is used, but I defined /usr/
as prefix!
Most of the not found libaries exist on my machine, but make looks
them up in the wrong directory!
What shall I do???

BIG THANKS FOR ALL YOUR ANSWERS IN ADVANCE!!!
