I disagree with adding /usr/sfw to the default paths that are
searched. what if you have another installation of it somewhere else
and want to use that one? this approach closes doors for other sysadmins
who may not wish to use /usr/sfw mysql.

the right way to do this is to set CPPFLAGS/CFLAGS/LDFLAGS in your
environment when you call configure. configure will then find the
libraries and headers in exactly where you've told it to.

leaving things to chance by trying to be smart about auto detecting
stuff in configure is almost always fraught with danger, and at the
very least it can make life difficult for others.

I am guessing that -R is not used because it is not portable across
all platforms that Dovecot should be able to be built on. again, this
is why you should use LDFLAGS.

"the administrator knows better than the configure script." :)

and I speak as someone who runs dovecot in a production Solaris
environment (though without mysql). mmm, pkgsrc :)

grant.
