This is an example from configure failure with ABI=x86 for cvs-1.12.12-r6 last lines from configure: checking for ssh... ssh checking for vim... /bin/nano checking for temporary directory... /tmp checking security/pam_appl.h usability... yes checking security/pam_appl.h presence... yes checking for security/pam_appl.h... yes checking for pam_start in -lpam... no configure: error: Could not find PAM libraries but the headers exist. Give the --disable-pam option to compile without PAM support (or fix your broken configuration) !!!
