Hi Alexandr,

Since you're working on 5.5.33a it would be great if you could
incorporate the patches I just submitted to allow building mariadb
using clang's libc++ http://www.freebsd.org/cgi/query-pr.cgi?pr=182408 .

As for your problem, there's been an ldconfig bug in the ports tree a
few days ago, maybe updating it will fix this for you (this is just a
wild speculation, I didn't really check if it is related). Feel free
to send me a tarball of the port skeleton off-list in case you're stuck.

Cheers,
Michael
