I noticed that too on Linux. Didn't pay attention. But in OSX
the library seems to load. Is it because of problems with
dynamic linking?

This is a repeat message;  
I have noticed of late that I am no longer getting graphs but just
ascii pictures.  I have just noticed when attempting to run
examples/fl.csd that I get the error message

This is clearly a symptom of a major problem.  The error message is
way too terse.  i assume that there is a missing library in FLTK but
this whole area has changed so much that I cannot even start to find
where this happens.  Please could whoever broke this please please fix
it!

I cannot reproduce this error. It is possible that a library on which
libwidgets.so depends is not found; try running ldd to find out what
dependencies may possibly be missing. For example:

ldd ./libwidgets.so
         linux-gate.so.1 =>  (0xffffe000)
         libsndfile.so.1 => /usr/local/lib/libsndfile.so.1 (0x40037000)
         libfltk.so.1.1 => /usr/local/lib/libfltk.so.1.1 (0x40091000)
         libstdc++.so.6 => /usr/local/gcc-4.1.0/lib/libstdc++.so.6 (0x4011b000)
         libpthread.so.0 => /lib/tls/libpthread.so.0 (0x40202000)
         libm.so.6 => /lib/tls/libm.so.6 (0x40214000)
         libgcc_s.so.1 => /usr/local/gcc-4.1.0/lib/libgcc_s.so.1 (0x40237000)
         libc.so.6 => /lib/tls/libc.so.6 (0x40241000)
         libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x40358000)
         libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40366000)
         /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
         libdl.so.2 => /lib/libdl.so.2 (0x40462000)

Ignore previous message.  The error was that the widgets.cpp was not
compiled with the correct libraries, as this was wrong in SConstruct.
I found where to give a proper error message rather than the "cannot
load" one and then chased.  My fix may not be optimal but it actually
works.
