Latest erlang ( 10.2.10 ) The configure scripts giving me lib/erl_interface/config.log get an error for not finding pthread/mit/pthread.h and then nptl/pthread.h . After this the whole process of configure "explode" and system crash. The whole report is at gentoo bugzilla at: http://bugs.gentoo.org/show_bug.cgi?id=131094 Regards, Matteo
