I started a while back by tweaking the configure script, and noticed Martin's tree, made a copy of _that_, and eliminated most of the unnecessary stuff. Since I'm not going to publish _that_ tree (I maintain ncurses), it would be of limited use. So (referring to PDCurses 3.4) this line in the configure script is the problem: mh_lib_dirs="$x_libraries `echo "$ac_x_includes $ac_x_header_dirs" | sed s/include/lib/g`" The problem is that 64-bit machines nowadays generally use lib64 - not lib, as the script assumes. When I tweaked it by hand, I just edited that line. mh_lib_dirs="$x_libraries `echo "$ac_x_includes $ac_x_header_dirs" | sed s/include/lib64/g`" But I prefer packages... Refreshing my memory, I see that Martin may not have _fixed_ that. But I did, using a script in the debian/rules file.
