fltk is not detected from source builds of rakarrack (and i imagine its broken everywhere else)
Steps to Reproduce:
2../configure in rakarrack untar dir
fltk not found, even though its installed
fltk found... rest of config & compile happens
./configure --prefix=/usr && make && su -c 'make install'
for fltk source dir = fltk found.... its gentoo specific. it should work the same for both and does not.
That package is most likely not using fltk-config.

We can't fix build systems for which we don't have ebuilds.
