[Dovecot] try to compile dovecot 2.0.11 with ssl support

[easy]

Hello,

I try to compile dovecot in Version 2.0.11 with ssl support on a CentOS 
4.5 system.
Installed packages are openssl and openssl-devel.

after "./configure --with-ssl=openssl" "make" "make install"the message is:
(also tried with CPPFLAGS="-I/opt/openssl/include" 
LDFLAGS="-L/opt/openssl/lib -ldl")

     Install prefix . : /usr/local
     File offsets ... : 64bit
     I/O polling .... : epoll
     I/O notifys .... : dnotify
     SSL ............ : yes (OpenSSL)
     GSSAPI ......... : no
     passdbs ........ : static passwd passwd-file shadow checkpassword
                      : -pam -bsdauth -sia -ldap -sql -vpopmail
     userdbs ........ : static prefetch passwd passwd-file checkpassword nss
                      : -ldap -sql -vpopmail
     SQL drivers .... :
                      : -pgsql -mysql -sqlite

so it looks like SSL support is included, but when I start dovecot the 
message is:

     # 2.0.11: /usr/local/etc/dovecot/dovecot.conf
     # OS: Linux 2.6.18-128.1.1.el5.028stab062.3ent i686 CentOS release 
4.5 (Final)
     passdb {
       driver = pam
     }
     protocols = imap
     ssl_cert = </etc/ssl/certs/dovecot.pem
     ssl_key = </etc/ssl/private/dovecot.pem
     userdb {
       driver = passwd
     }
     doveconf: Error: SSL support not compiled in but ssl=yes
     doveconf: Fatal: Error in configuration file 
/usr/local/etc/dovecot/dovecot.conf: SSL support not compiled in but ssl=yes

I also tried to use the source files of openssl and compile openssl by 
myself, but the error is the same.

thanks
