Commit 786e248c 2012-12-01 breaks tdebase in GIT

Hi I cloned myself a copy of tde yesterday and tried to compile it on Slackware64 14.0. (I use the Slackware build scripts available at http://humanreadable.nfshost.com/sdeg/trinity_desktop.htm.) All went well until I was compiling tdebase, when it crashed and burned with: Generating tdmadmindialog.moc cd /tmp/tdebase.build/tdm/kfrontend && /usr/bin/tmoc /tmp/tdebase/tdm/kfrontend/ tdmadmindialog.h -o /tmp/tdebase.build/tdm/kfrontend/tdmadmindialog.moc /tmp/tdebase/kdesktop/lock/backtrace_symbols.c:57:22: fatal error: demangle.h: No such file or directory compilation terminated. Slackware does not have demangle.h (nor does an Ubuntu 12.04 that I have lying around). Is there some other package which has been added as a pre-requisite with that commit? Or is there some way to change that patch so that we don't actually need that file? Thanks. Jim
