However, Jeanette could rebuild the package. The PKGBUILD is available by ABS [1] and it could be downloaded from https://git.archlinux.org/svntogit/packages.git/plain/trunk/PKGBUILD?h=pack… , too. The makepkg config is located in /etc/makepkg.conf Would strace or gdb or something else show what's going on? FWIW for gdb usage packages need to be build with options=(debug !strip). "These settings will force compilation with debugging information and will disable the stripping of debug symbols from executables. To apply this setting to a single package, modify the PKGBUILD: options=(debug !strip)" - https://wiki.archlinux.org/index.php/Debug_-_Getting_Traces Regards, Ralf [1] https://wiki.archlinux.org/index.php/Arch_Build_System
