but dovecot's configure script does not allow to specify the
mysql libs and headers explictly - only by global CPPFLAGS and
LDFLAGS extensions, which are used for all binaries - when i
tried to specify:

./configure --prefix=/opt/dovecot --sysconfdir=/etc/dovecot --mandir=/opt/dovecot/man \
	--docdir=/opt/dovecot/doc --libexecdir=/opt/dovecot/sbin --datadir=/opt/dovecot \
	--with-rundir=/var/dovecot/run --with-statedir=/var/dovecot/state \
	--with-mysql=/opt/mysql/bin/mysql_config
checking for ...
checking pkg-config is at least version 0.9.0... yes
configure: error: --with-mysql=path not supported. You may want to use instead:
CPPFLAGS=-I/opt/mysql/bin/mysql_config/include LDFLAGS=-L/opt/mysql/bin/mysql_config/lib ./configure --with-mysql

i followed the hint from the configure script above and run
into the core-dumps due to symbol clash str_to_time.

How to work around with mysql in non-standard location?
