the IUP egg depends on the ffcall library [1] in order to be able to construct
function pointers which can be registered as IUP callbacks and which forward
their arguments to a Scheme procedure. It is likely that this library is missing
on your system if the above message appears even though IUP is installed and
can be found by the C compiler and linker.

I admit that the warning message is stupid and I have therefore changed it in
the trunk version of the egg, but I haven't tagged a new release of the egg
because I also modified other minor things that depend on changes in CHICKEN
