Is this where you're seeing it?

   1902         /* Open output fille */
   1903 #if (__GLIBC__ >= 2) && (__GLIBC_MINOR__ >= 1)
   1904         outFileNum = open(ofname, O_RDWR | O_CREAT | O_EXCL | O_NOFOLLOW);
   1905 #else
   1906         outFileNum = open(ofname, O_RDWR | O_CREAT | O_EXCL);
   1907 #endif

(It's the only place where I could find the string 'O_NOFOLLOW'.)

Maybe there's a problem with the #if stmt, or maybe theres some difference
between your libc.so and your devel headers (i.e. devel headers are for a
newer version of glibc than the one that is on your system).
