That's a rather critical problem, considering these are core PAM functions. You also say that applications fail with > ../../libpam/libpam.so: undefined reference to `pam_get_item' > ../../libpam/libpam.so: undefined reference to `pam_set_item' ... which means that the PAM library itself is looking for these functions and can't find them. Upstream bug or not, this .so is totally screwed; this isn't something you can patch around by choosing not to build stuff. -- Steve Langasek postmodern programmer
