build fails courierpassd-1.1.0-RC1

[Ed Stover]

I have been trying to compile courierpassd-1.1.0-RC1 on FreeBSD4.11
I have courier-authlib-0.51 from packages.
 from my make of  courierpassd-1.1.0-RC1
gcc -DHAVE_CONFIG_H -I. -I. -I.     -g -O2 -c courierpassd.c
In file included from courierpassd.c:38:
courierpassd.h:24: courierauth.h: No such file or directory
courierpassd.h:25: courierauthdebug.h: No such file or directory

any ideas? or has any one got a mysql+qmail+vpopmail setup that allows
users to change there passwords from Squirrelmail?
