Note:
-----
latest update of libjpeg-turbo breaks the building of most dependent
ports, because they switched from the autools build system to cmake
and no longer installs the libtool file libjeg.la which other ports
used to link libjpeg.
It's sufficient to rebuild libtiff if the following error pops up:
...
/bin/sed: can't read /usr/lib/libjpeg.la: No such file or directory
libtool: error: '/usr/lib/libjpeg.la' is not a valid libtool archive
