Summary:  printf() requires function 'puts()' in some cases

Original Submission:  printf() in avr-libc?  Bestill my heart!  I love it.  
However, I have found this anomaly:  When the format string does NOT contain 
"\n" new line character, everything works well.  If the format string DOES 
contain "\n", then the linker fails, citing an "undefined reference to puts()". 
 Do I need to include my own version of puts(), just as I included my own 
version of (in this example) uart_putc & uart_getc?  Thanks for the help.
