startkde fail

After some compilation with slackware 13.37 kde start failed with message "Could not start ksmserver. Check your installation.".

Fix (link):
In /usr/bin/startkde, change the line similar to
LD_BIND_NOW=true /usr/lib/kde4/libexec/start_kdeinit_wrapper +kcminit_startup
by removing the LD_BIND_NOW=true clause, leaving just
/usr/lib/kde4/libexec/start_kdeinit_wrapper +kcminit_startup
