Thanks.  The gcc command came out of O'reilly book "MySQL & mSQL".  
After sending this, I kept looking and found libmysqlclient.a, 
leading to your answer.  And I do have glibc ver 2.2.4 (plus devel 
pkg) installed.  Great, except without the -lsocket param, I get 
unresolved references to 'compress' and 'uncompress' from a mysqllib 
routine.  I found many references to those routines in many lib*.a's 
so they should be resolved somewhere!, shouldn't they?
