Building Qqis on -14.2: lpthreads not found

Building qgis fails and the error is at the end of the CMakeError.log file. Because that's 216 lines long it's available for downloading from <http://www.fileconvoy.comdfl.php?id=ge9fe28eccb2ec8601000381459b53805e0fcc2fe88> and will be available for 5 days.

I could not find lpthreads on my system nor in the SBo repo.

Please advise me where I can find a copy to install, or in what package that is to be found.

TIA,

Rich
