without-bdb error on 2.3.0 version

[Patrice]

Hi,

I have a little problem with the compilation of cyrus-imap 2.3.0

here is the error:

In file included from auth_pts.c:57:
auth_pts.h:56:16: db.h: No such file or directory
make[1]: *** [auth_pts.o] Error 1
make[1]: Leaving directory `/sources/cyrus-imapd-2.3.0/lib'
make: *** [all] Error 1



and the configure:
./configure --without-bdb

this option of compile works well on 2.2 series


thank you

Patrice
