Can you check whether there is (or has ever been) also a version of fltk-1.1.x on the failing machine? If so, you need to (somehow) ensure that the include path picks up the headers for fltk-1.3 and *only* the headers for fltk-1.3... The headers for 1.1. and 1.3 are not "versioned" and are similar enough that the code can often still build "OK" with the wrong headers and prototypes, but then bork horribly at runtime. This *looks* a lot like what you are seeing, though I may well be wrong!
