(#:/work) dpkg -i libc6_2.1.3-20.deb dpkg: `ldconfig' not found on PATH. dpkg: 1 expected program(s) not found on PATH. NB: root's PATH should usually contain /usr/local/sbin, /usr/sbin and /sbin.   ([EMAIL PROTECTED])(/dev/pts/4)(19:53:46)(Thu May  2)(6)(1) (#:/work) locate ldconfig ....doesn't find it.   So, what do i have to install to get ldconfig.. Sorry for being such a newbie.   Tuomo Karhu
