Hello, I have a reproducible problem with virtualbox on my system. To find out which version was the first one that causes those problems for me, I want to build virtualbox on my own and step back until the problem no longer exists. I've checked out the community PKGBUILD's using git. If I try to build virtualbox, it always ends with the following messages: kmk_builtin_rm -f /home/build/git/community/virtualbox/repos/community-x86_64/src/VirtualBox-4.2.6/out/linux.amd64/release/obj/webservice/gsoap_copy_all_ts kmk_builtin_mkdir -p /home/build/git/community/virtualbox/repos/community-x86_64/src/VirtualBox-4.2.6/out/linux.amd64/release/obj/webservice/demo_soapxml /home/build/git/community/virtualbox/repos/community-x86_64/src/VirtualBox-4.2.6/out/linux.amd64/release/obj/webservice/demo_headers /home/build/git/community/virtualbox/repos/community-x86_64/src/VirtualBox-4.2.6/out/linux.amd64/release/obj/webservice/demo_namespacemaps kmk_builtin_mv -f /home/build/git/community/virtualbox/repos/community-x86_64/src/VirtualBox-4.2.6/out/linux.amd64/release/obj/webservice/demo_headers usage: kmk_builtin_mv [-f | -i | -n] [-v] source target or: kmk_builtin_mv [-f | -i | -n] [-v] source ... directory or: kmk_builtin_mv --help or: kmk_builtin_mv --version kmk: *** [/home/build/git/community/virtualbox/repos/community-x86_64/src/VirtualBox-4.2.6/out/linux.amd64/release/obj/webservice/gsoap_copy_all_ts] Error 64 kmk: *** Waiting for unfinished jobs.... info: soapC-1.cpp info: soapC-2.cpp info: soapC-3.cpp info: soapC-4.cpp info: soapC-5.cpp info: soapC-6.cpp info: soapC-7.cpp info: soapC-8.cpp info: soapC-9.cpp info: soapC-10.cpp info: soapC-11.cpp info: soapC-12.cpp info: soapC-13.cpp info: soapC-14.cpp info: soapC-15.cpp info: soapC-16.cpp info: soapC-17.cpp info: soapC-18.cpp info: soapC-19.cpp info: soapC-20.cpp split-soapC: Created 20 files. kmk: *** Exiting with status 2 ==> ERROR: A failure occurred in build().
