To Gordon's comment, I can verify that when put the 'nisplus' entry back 
into nsswitch.conf (by editing it), the problem comes back.

I'm not running NIS/NIS+ either..  After reading your followups, I 
looked through my installed packages and found yp-tools, ypbind, and 
ypserv and uninstalled them all, however name resolution still breaks if 
I put nisplus back into nssswitch.conf (not that I need it -- I'm just 
curious).  It's not clear to me which is the 'nisplus module' that 
Ulrich is refering to, though I did notice fetchmail pulled in 
/lib/libnss_nisplus.so.2 (provided by glibc) during the failed system call.
