[Dovecot] ignors the configure prefix

1.2.5 is ignoring the configure -prefix switch. It you install it some place else with the -prefix then I get errors all over the place becuase things are hard coded to use the default and it can't find anything any more like:

Fatal: execv(/usr/local/libexec/dovecot/ssl-build-param) failed: No such file or directory

and

Error: Can't open configuration file /usr/local/etc/dovecot.conf: No such file or directory Fatal: Invalid configuration in /usr/local/etc/dovecot.conf

and

Starting Dovecot Imap: Error: auth_executable: Can't use /usr/local/libexec/dovecot/dovecot-auth: No such file or directory

How do I fix this?
