Aside from any questions about whether the configuration scripts are doing their 
thing, one way to find a lib file which references that symbol is to trawl your 
libs and perform the Unix command "nm" on each. I seem to have that symbol in 
/usr/lib/libnsl.so on an Ultra. Here's a script I use:

------------------------------ <cut here> ---------------------------------

#!/bin/sh

# Usage: script_name <symbol> <root directory> 
# where  
# <symbol> is what we want "nm" to look for  
# <root directory> is where to initiate a recursive find 
 
if (test "$#" != 2) then 
        echo "Usage: script_name <symbol> <root directory>" 
        exit 
fi 
 
 
main()
{
arg1=$1  
 
while (test "$2" != "") do
        line=`nm $2 | grep $arg1`
        if (test "$line" != "") then 
                echo $2
                echo $line
                echo
        fi
        shift 
done   
}
  
so_files=`find $2 -name '*lib*.so' -print`   
a_files=`find $2 -name '*lib*.a' -print` 
main $1 $so_files $a_files
