Hi Petr, As suggested on my patch 77, I would prefer get rid of ucred declaration. This piece of code is completely outdated and used on older glibc. On GNU/kFreeBSD, it seems still an issue ? afaics, the ftbfs isn't caused by ucred structure: /bin/sed: can't read /usr/lib/libjack.la: No such file or directory libtool: link: `/usr/lib/libjack.la' is not a valid libtool archive cheers, Fathi
