Thanks Ben, but that's all I have on my Ultra 1 ii libpam-modules 0.72-35 Pluggable Authentication Modules for PAM ii libpam-runtime 0.72-35 Runtime support for the PAM library ii libpam0g 0.72-35 Pluggable Authentication Modules library There is unfortunately no pam_modules.h or libpam0g-dev What am I doing wrong ? Where can I find libpam0g-dev for Sparc ? regards, Jan
