I also reported this problem to gnuplot's maintainers as bug #615289 before I found how many programs is depend on libtiff.so.3 on my system.
With Julien's help I have discovered that gnuplot gets dependencies from old libraries in /usr/local: $ ldd /usr/bin/gnuplot | grep /usr/local libwx_gtk2u_core-2.8.so.0 => /usr/local/lib/libwx_gtk2u_core-2.8.so.0 (0xb7bad000) libwx_baseu-2.8.so.0 => /usr/local/lib/libwx_baseu-2.8.so.0 (0xb7a60000) Programs in /usr/local are too important for me so I can't delete them. I found the next solution: $ export LD_LIBRARY_PATH=/lib:/usr/lib Then gnuplot runs normally in this terminal session. Is it normal that Debian's programs in my system gets dependencies from non-Debian libraries? In this situation each new installation in /usr/local is a venture with unpredictable results. Any Debian's program can stop work or can begin work in unexpected way after installation of new program in /usr/local. It makes Debian unreliable system. ------------------- Regards, Sergey -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
