I recently load a fresh ports tree to /usr/ports. Same error. I still don't
know, which part of the port looks for "SASL2" (file or directory). 

I also tried a package ... that works, but is not build with SASL2-support.
Can I get a postfix(-current) package for FreeBSD 4.10 / 4.11 build with
SASL2 support somewhere?
