I should clarify that.  At compile time all external references must be
satisfied which is done by searching through glibc and any other 
specified libraries.  Since glibc-3.2.2 incorporates libintl all such
references are satisfied and the compiler does not notice that libintl
does not exist.  However, the -lintl flag sets a reference in the
compiled code which tells the linker to load libintl.so.1 at run time,
it can't so the program fails to run.

Like I said, this is a heads up, especially if this hint is going to be
included in the book as our de facto build method.
