I do now. This one was really tricky ;) The check for FTGL/ftgl.h is good, the 
test for ftgl.h fails. With this fail the variable warn_graphics ist set to the 
string

  warn_graphics="FTGL library not found. Native renderer will not have 
on-screen text"

The variable warn_graphics is used later for the test of fltk - all fltk tests 
are good but warn_graphics is still set. Finally we get to the line 730 in 
configure.in

  if test "x$warn_graphics" = "x" ; then
    ->good
  else
    ->bad

and I get into ->bad because the check for ftgl.h failed (long before).

My solution resp. my suggestion would be to initialize warn_graphics once again 
for the test of fltk. A changeset for this is attached.
